libaom: 3.0.0 -> 3.1.0
We had to use fetchgit so far as the tarballs are generated on demand
and have embedded timestamps which makes their hashes unstable [0][1].
This is a problem for fetchurl but fetchzip extracts the tarballs into
the Nix store and therefore the contents will get normalized and the
hashes remain stable.
