Since I8eb28584e90ad012cbf7f3175ee3a8e775c8d523, the test suite
is supposed to run both BTS_Tests_{SMSCB,LAPDm}.control among with
BTS_Tests.control. Apparently this requires more time than 3600
seconds, so everything is broken since build #2652 in Jenkins.

This content is mostly specific to sysmocom's setup (thought it can
still be re-used by other people if willing to).
symlinks in ttcn3/ pointing to example/ are redone to point to
sysmocom/.
