mesa: bump to 9.0.1

Upgrade Mesa to 9.01, backporting a patch from master to build without needing
mesa-dri-glsl-native.

Several patches have been merged upstream, so drop them.

License checksums updated as the file was re-formated.

Drop mesa-dri-glsl-native as we don't need it anymore.

Tested with Piglit's "quick" test suite, pass rate remains constant compared to
8.0.5 at 87%.
