Change subject: msc_vlr_tests: GSUP: don't care about extra IEs

msc_vlr_tests: GSUP: don't care about extra IEs

To not break the msc_vlr tests by new GSUP IEs added to some of the GSUP
messages, make msc_vlr_tests only match the start of the GSUP message and not
care about extra IEs. The extra IEs are anyway seen in the expected logs.

The reason to drop the msgb_eq_data_print() is because it is useless for
mismatching lengths. It will always print only the length mismatch, instead we
need to be able to compare with what was expected.
