dev-build/gn: add 0.2200-r1; update Live

The -r1 ebuild has an updated patch that does not
remove `-DNDEBUG` from CFLAGS in the non-debug build
path.

This has not caused issues before however current Chromium
builds that are otherwise fine fail asserts resulting in
messages like:

`FATAL:command_gen.cc(###)] Check failed: !rule.empty().`

It is expected that this will eventually be resolved by
changes to GN or Chromium. For now, Chromium builds
and upstream don't seem to be running into any
issues with using very similar commits as part of
their current DEPS file.
