Extend the existing test case to cover:
1. Invalid flag atribute in the struct drm_mode_fb_cmd2.
2. Pixel format which requires non-linear modifier with
DRM_FORMAT_MOD_LINEAR set.
3. Non-zero buffer offset for an unused plane

Also replace strcpy to strscpy on test_to_desc for improved security
and reliability.

I believe this change should be done in a separate patch.
