Subject: [PATCH] feat(ops/nixos/nugget): Add chromium with VAAPI patches

These patches enable hardware-accelerated video decoding, which is
useful for Stadia.

The main issue with this is that Hydra doesn't currently cache
Chromium with these patches, which means that it is built from scratch
which takes in the order of 5 hours on an otherwise unused nugget.
