units: remove test-bitmask and add UNIT_TEST instead
This moves the code in test-bitmask into a UNIT_TEST() directly in cogl-bitmask.c which will now be run as a tests/unit/ test. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 693c85e0cde8a1ffbffc03a5f8fcc1f92e8d0ac7) Includes fix to build conform tests with -I$(top_builddir)/cogl to be able to find cogl-gl-header.h
