bsc_test: drop "scan to MSC" code path

The TEST_SCAN_TO_MSC is completely unused, but still the code linked
bsc_scan_bts_msg() for the unused code path. This is unlikely to ever be
expanded. Remove TEST_SCAN_TO_MSC and reduce linking requirements.

(I am this close to dropping the test entirely to avoid continuous linking
annoyance, but ok, since nothing else tests timezones AFAIK, keeping it.)
