chromium: Disable VA-API by default

This is done to avoid driver specific issues and restores the previous
behaviour. Like before video acceleration can be enabled without having
to rebuild Chromium.

-Subject: [PATCH] Enable accelerated video decode on Linux
-
-This will enable accelerated video decode on Linux by default (i.e.
-without "--ignore-gpu-blacklist"), but on NixOS we'll provide
-"--disable-accelerated-video-decode" and
-"--disable-accelerated-video-encode" by default to avoid regressions
-(e.g. VA-API doesn't work properly for some radeon drivers).
-
-Video acceleration can then be enabled via:
-chromium.override { enableVaapi = true; }
-without rebuilding Chromium.
