chore(3p/sources): Bump channels & overlays

Upstream nixpkgs removed a lot of aliases this time, so we needed to do
the following transformations. It's a real shame that aliases only
really become discoverable easily when they are removed.

* runCommandNoCC -> runCommand
* gmailieer -> lieer
  We also need to work around the fact that home-manager hasn't catched
  on to this rename.
* mysql -> mariadb
* pkgconfig -> pkg-config
  This also affects our Nix fork which needs to be bumped.
* prometheus_client -> prometheus-client
* rxvt_unicode -> rxvt-unicode-unwrapped
* nix-review -> nixpkgs-review
* oauth2_proxy -> oauth2-proxy

Additionally, some Go-related builders decided to drop support for
passing the sha256 hash in directly, so we need to use the generic hash
arguments.
