[PATCH i-g-t] tests/intel/gem_eio: Fix SIGABRT in kms subtest

[Kamil Konieczny]

Subtest kms runs display helper in a separate process, which in
turn prepares patterns for screen and there makes additional
checks resulting in skip. This leads to a SIGABRT as igt_core
require all such skips in main process, not in child.

Add this check before starting a kms subtest, also move other
skip checks into one place.
