Fix#96897 and fix#92751.
This reverts commit 5da66561d1.
It seems the chromium build now unconditionally tries to enable ozone
(even though we disable it), causing the build to fail (as we only
provide xkbcommon when enabling Ozone):
```

update.nix was a huuuuge hack, abusing checksum collisions, etc., and
was extremely difficult to read and maintain, especially because
values from update.nix were also used in the derivations themselves!
I've replaced this with an implementation in Python, which I chose for
readability. Rather than generating Nix, I chose to
generate JSON, since Python can do that in the standard library and
Nix can read it.
I also set update.py as an updateScript, so Chromium can now
automatically be updated!

Note: The following might also need to be updated:
substituteStream(): WARNING: pattern '/usr/share/xcb' doesn't match anything in file 'ui/gfx/x/BUILD.gn'
I didn't look into this yet but IIRC M86 will finally have a flag for
Linux to enable VA-API. So we shouldn't need
enable-video-acceleration-on-linux.patch anymore.
But we likely need to update enable-vdpau-support-for-nvidia.patch
when/before M86 hits the stable channel if we want to keep VDPAU
support.
Ok, so I was about to update the patch (didn't apply anymore) when I
also started looking at it's usage and realized that
NIX_CHROMIUM_PLUGIN_PATH_ (and other substrings) only appears in the
patch itself (i.e. it seemed like we don't need this patch anymore).
Turns out that we have this patch since 2014 (1b84fbf0ca) and it was
only ever used for NIX_CHROMIUM_PLUGIN_PATH_WIDEVINE (and from the log
it isn't clear if/when or how well that worked). But in 2019 that last
usage got removed (545d58a1ef) so we should be able to safely drop this
patch now :) \o/
(I just wanted to note that as it seemed somewhat of a funny story :D
But there is of course nothing wrong with it.)

This is more robust than depending on the channel, though the version
should only matter if the configuration phase fails.
This also switches to the intended version for `chromium` which should
be higher since M85 is in the stable channel.
Thanks `@volth` for pointing this out.
