The wayland EGL platform sets the modifier count to 0 in some cases
to signal that modifiers should not be used, even if a list of modifiers
is present. The loader_dri_create_image helper didn't handle this case
properly and called the modifierful driver interface with a 0 modifier
count, leading to the obvious outcome of the driver being unable to
allocate an image.

The DRI image extension already has two different ways to allocate an
image (with and without a modifier) and will soon grow a third one.
Add a helper, which handles calling the appropriate implementation to
get rid of code duplication in the winsys.
This convert the two obvious call sites (GBM dri and EGL wayland)
that profit from the code dedup.
