msc_vlr_tests: revert IMSI parameter and test nr output

Three recently merged commits take the msc_vlr_tests in a wrong direction.

The IMSI is usually encoded in the hex streams. The rationale behind hex
streams is that it is a) easily copied from a wireshark trace and b) exactly
the bytes as sent by an actual phone. It is hard to parameterize the IMSI
because we would have to employ our encoding functions, which I intentionally
want to keep out of the loop here.

The test number should not appear in the normal test output, so that adding a
test or changing their order does not affect expected output for following
tests. The nr is simply for manual invocation, only seen when invoked with -v.
