debian/*.install: make paths consistent

Some of the paths start with a leading slash and some don't. Both
variants work, but this is confusing. Let's go without the leading
slash, because the paths are releative (in this case to debian/tmp where
"make install" puts the files during debian packaging).

build: install common/GSM/transceiver libraries for emscripten and add pkg-config files

Expose previously internal libs (libcommon, libGSM, libtransceiver_common)
when building with emscripten, install headers and generate .pc files.
Keep them noinst for native builds.

checkpatch.conf: lint more code

The current linter configuration misses to find lots of formatting
errors as we've seen here:
https://gerrit.osmocom.org/c/osmo-trx/+/42198/comments/f8f1b5a2_3c7e1389

This is caused by the following exclude rules in .checkpatch.conf, which
were added there to avoid that some of the checkpatch rules don't work
correctly with C++ code:

  ---exclude .*h
  ---exclude Transceiver52M/grgsm_vitac/.*
  ---exclude utils/va-test/.*

Fix this by splitting the .checkpatch.conf into two files,
.checkpatch.c.conf and .checkpatch.c++.conf. Let the C version use the
default rules. Let the C++ version ignore the rules that don't work with
C++ code:

* SPACING
  Fails on:
    std::vector<std::string>
  With:
    ERROR:SPACING: spaces required around that '<' (ctx:VxV)
    ERROR:SPACING: spaces required around that '>' (ctx:VxW)

* FUNCTION_ARGUMENTS
  Fails on:
    ScopedLock lock(mLock);
  With:
    WARNING:FUNCTION_ARGUMENTS: function definition argument 'mLock' should also have an identifier name

* INDENTED_LABEL
  Fails on:
    private:
    protected:
  With:
    WARNING:INDENTED_LABEL: labels should not be indented

* NEW_TYPEDEFS
  Fails on:
    typedef std::map<K,D*> Map;
  With:
    WARNING:NEW_TYPEDEFS: do not add new typedefs

With the new config, the linter only complains about the following
things across the existing C++ code, which seem to be legitimate linting
problems (and if not, can be ignored as well):

  BRACES_NOT_NECESSARY, CODE_INDENT, LEADING_SPACE,
  MULTISTATEMENT_MACRO_USE_DO_WHILE, OPEN_BRACE, POINTER_LOCATION,
  PRINTF_I_OSMO, SINGLE_STATEMENT_DO_WHILE_MACRO, SPACE_BEFORE_TAB,
  STATIC_CONST_CHAR_ARRAY, TABSTOP, TRAILING_WHITESPACE

checkpatch.conf: lint more code

The current linter configuration leads to too many linting errors, as
seen here:
https://gerrit.osmocom.org/c/osmo-trx/+/42198/comments/f8f1b5a2_3c7e1389

Fix this by not excluding files where the linter generates false
positives. But instead ignoring specific rules that generate these false
positives (mostly related to this being a C++ code base). The following
rules are now ignored:

* SPACING
  Fails on:
    std::vector<std::string>
  With:
    ERROR:SPACING: spaces required around that '<' (ctx:VxV)
    ERROR:SPACING: spaces required around that '>' (ctx:VxW)

* FUNCTION_ARGUMENTS
  Fails on:
    ScopedLock lock(mLock);
  With:
    WARNING:FUNCTION_ARGUMENTS: function definition argument 'mLock' should also have an identifier name

* INDENTED_LABEL
  Fails on:
    private:
    protected:
  With:
    WARNING:INDENTED_LABEL: labels should not be indented

* NEW_TYPEDEFS
  Fails on:
    typedef std::map<K,D*> Map;
  With:
    WARNING:NEW_TYPEDEFS: do not add new typedefs

With the new config, the linter only complains about the following
things across the existing code, which seem to be legitimate linting
problems (and if not, can be ignored as well):
