lib/igt_debugfs: s/igt_pipe_crc_check/igt_require_pipe_crc/

Functions which provide feature checks through igt_skip should be of
the form <prefix>_require_<feature>.

Otoh feature checks which return in a boolean whether the feature is
available should be of the form <prefix>_has_<feature>, e.g.
gem_has_blt.
