gem_flink_race/prime_self_import: Improve test reliability
gem_flink_race and prime_self_import have subtests which read the
number of open gem objects from debugfs to determine if objects have
leaked during the test. However the test can fail sporadically if
the number of gem objects changes due to other process activity.
This patch introduces a change to check the number of gem objects
several times to filter out any fluctuations.
v2: Moved the common code to a library and made the loop android
specific (Daniel Vetter)
v3: Renamed get_stable_obj_count -> igt_get_stable_obj_count
