Revert "Re-enable AImageReader on ARM GPUs."

This reverts commit f7de2bf8.

Reason for revert: b/143771201

Original change's description:
> Re-enable AImageReader on ARM GPUs.
>
> Re-enable AImageReader on ARM GPUs since few bug fixes related to
> memory regressions have been landed and we expect those fixes
> might have also fixed the crashes we were seeing with ARM GPUs.
>
> Will need to revert this CL if it causes crashes. Since the crashes are
> not reproducible locally, there is no other way to test this expect
> removing the GPU family from the blacklist and hence enabling it on
> ToT.
