[Intel-gfx] [PATCH i-g-t 2/2] kms_plane_scaling: Find the image regardless how the test is run

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

As it stands running the test like "sudo tests/kms_plane_scaling"
does not work.

Fix it by using the same method igt_paint_image uses.
