glupload: Fix NXP's transform_caps
NXP added a fast dmabuf upload path that depends on Vivante features.
In this mode input is converted to RGBA backed by a single EGLImage so
they changed transform_caps to hard coded RGBA. They however didn't:
* remove colorimetry and chroma-site from the caps which doesn't make sense
for a non planar format like RGBA. This leads to downstream warnings
like "invalid matrix 3 for RGB format, using RGB" to be produced for
every frame.
* change upstream caps transform at all leading to allocation query
mismatches. This is most obvious when a tee is present since it now
aggregates allocation queries. At least one downstream tee branch
gets the wrong caps with subsequent all 0 pixels when frame is mapped.
Cherry-picked from upstream implementation of the same feature:
