st/mesa: fix ReadPixels into packed formats with PBO
When using the GPU download path, we bind the PBO as a buffer texture,
so call is_format_supported accordingly. On radeonsi, this means that
GPU downloads aren't used for UNSIGNED_SHORT_5_6_5 destinations, for
example.
Fixes parts of GL45-CTS.gtf32.GL3Tests.packed_pixels.packed_pixels_pbo.
