[PATCH i-g-t 4/9] lib/igt_drm_fdinfo: Copy over region map name on match

[Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxxxxxxx>]

From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

I will need some record of which regions were found for intel_gpu_top so
lets just copy over the region name from the map on the first match.
