ttcn3-bts-test/jenkins.sh: do not create unused directory

ttcn3-bts-test/jenkins.sh: use bts-tester-{generic,oml,virtphy,hopping}

Let's use separate directories to store the artifacts of different
TTCN-3 test case groups.  This would prevent the test suite from
overwriting *.log and *.pcap files when running both generic and
hopping configurations together, and simplify the overall hierarchy.

ttcn3-bts-test/fh: fix: properly include BTS_Tests.cfg

Include the correct configuration file, not the one from the image.

ttcn3-bts-test/fh: fix: do not run BTS_Tests.control twice

Apparently, TITAN concatenates the contents of all sections, so
we end up with the following set of test cases:

  [EXECUTE]
  BTS_Tests.control
  BTS_Tests_SMSCB.control
  BTS_Tests_LAPDm.control
  BTS_Tests.control

ttcn3-bts-test/fh: fix: properly rename classnames

Not only append ':hopping' to classnames equal 'BTS_Tests', but
also 'BTS_Tests_SMSCB' and 'BTS_Tests_LAPDm', so they would not
shadow non-hopping test cases in the test results analyzer.
