selftests/x86: Update the negative vsyscall tests to expect a #GP

Browse source

Some of the vsyscall selftests expect a #PF when vsyscalls are disabled.
However, with LASS enabled, an invalid access results in a SIGSEGV due
to a #GP instead of a #PF. One such negative test fails because it is
expecting X86_PF_INSTR to be set.

Update the failing test to expect either a #GP or a #PF. Also, update
the printed messages to show the trap number (denoting the type of
fault) instead of assuming a #PF.
