From: Deepak Rawat <drawat@vmware.com>

vmwgfx and amdgpu doesn't support fb modifiers, yet kms_addfb() requires
modifier support. Since many tests don't need this to run, the
requirement can be made less broad.

Therefore, tighten the requirement to cases where modifiers are actually
needed.

v2:
* In create_fb() calls to kms_addfb(), remove the modifier flag iff the
  driver doesn't support modifiers and the modifer is 0
* Don't modify the flag in kms_addfb().
