drm_prime: fix use of formats with modifiers 

Similar to handles the modifiers must be supplied for each plane of the
format or a framebuffer cannot be created.

Use the format_modifier tied to the object used for the plane to fix use
of formats with modifiers.

Also fix the improper use of the DRM_MODE_FB_MODIFIERS-flag for formats
without modifiers.

This fixes playback of videos decoded by e.g. rpivid into a NV12 format
using SAND128 modifer on RPi using the drmprime-overlay interop.
