[Intel-gfx] [RESEND PATCH i-g-t] tests/prime_vgem: Give meaningful messages on SKIP

[Janusz Krzysztofik]

Messages displayed on SKIPs introduced by commit 92caadb4e551
("tests/prime_vgem: Skip basic-read/write subtests if not supported")
don't inform clearly enough that those SKIPs are expected behavior.
Fix it.

Assuming the R-b: from Ewelina is sufficient, can someone push this,
please?  I can't do that myself as I have no push permissions.

Thanks,
Janusz
