linux-dmabuf: clarify DRM_FORMAT_MOD_INVALID
DRM_FORMAT_MOD_INVALID means to derive the modifier from the dmabuf.
It provides legacy support and makes it easier to replace wl_drm.
v3: DRM_FORMAT_MOD_INVALID must be advertised to be supported (which
requires a version bump)
v4: no version bump, but a note for now
