egl/wayland: Fix zwp_linux_dmabuf usage

There's no guarantee that the formats advertised by wl_drm and the formats
advertised by zwp_linux_dmabuf_v1 are the same.

get_back_bo() handles this by falling back from createImageWithModifiers() to
createImage() when there's a wl_drm format but no corresponding linux_dmabuf
format, but create_wl_buffer() unconditionally tries to create a linux_dmabuf
buffer unless DRIimage has DRM_FORMAT_MOD_INVALID.

Fix this by always checking if the DRIimage modifier has been advertised
by zwp_linux_dmabuf_v1, and falling back to wl_drm if not.

If DRM_FORMAT_MOD_INVALID has been advertised then we trust the client
has allocated something appropriate and treat any modifier as matching.
