Add igt_display_require_retry to re-try igt_display_require.

At entry of each test, display setup is done by
igt_display_require and igt_display_require_output.
igt display require output may not be valid yet,
this will let test be skipped. By re-try
igt_display_require, require output could be valid.
This will fix test case intermittent skip issue.
