gprs_gb: Fix compilation of tests

It's unsure if the tests do anything useful.   At least they build again

The fundamental problem is some clashes/overlap between our own
definitions for certain protocols and those that Ericsson released
later.  Ideally we should use Ericsson whenever possible and resort on
our own ones only as a fall-back for those that don't exist, but
significant development has been done before Ericsson released their
codecs, so it's TBD for the future.
