[PATCH i-g-t] lib/igt_device_scan: Skip attributes in subdirectories

[Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com>]

Skip attributes in subdirectories as they are not used for filtering.
This change improves speed and reduces the impact of non-DRM related
component bugs on testing, such as ASPM issues.

Rename function is_on_blacklist to is_on_blocklist to promote more
inclusive language.
