i965: Set modifier for imported and duplicated images
When a buffer is being created from FD or GEM flink import, the current
API makes no provision for passing modifier information along with this.
Set the modifier for such images to DRM_FORMAT_MOD_INVALID.
Also preserve the modifier when duplicating an image, as will be done by
GBM when importing from a wl_buffer.
This doubly tripped up Wayland, as the images would first have been
created (as wl_buffers) with a 0 modifier, and then lost what modifier
they would've had when being duplicated into gbm_bos.
Fixes: d78a36ea624 ("i965/dri: Handle the linear fb modifier")
