by Oliver Smithtestenv: improve --config argument parsing
* Support using wildcards for the config names via fnmatch as that makes
it much easier to run the ggsn tests against all osmo-ggsn config
variations, and update the examples in "testenv.py -h" to illustrate
this.
* Fix that it didn't complain about an invalid --config argument, as
long as there was a valid --config argument before it.
* Let raise_error_config_arg only output the invalid --config argument
instead of all of them.
* Complain if "--config all" is used in combination with another
--config argument.
* Sort testenv*.cfg files found alphabetically, so they are always
executed in the same order.
