lib/igt_kms: Fill the plane format/mod information for pre-blobifier drivers
For drivers that don't support the IN_FORMATS blob we should just
consult the format list returned by getplane. Since we can't know
which modifiers are supported we'll assume linear-only. Obviously
that may not work for every driver out there, but not much more
we can do unless we start to actually probing with addfb.
