Subject: [PATCH] libudev-zero: init at 1.0.0

libudev-zero is a daemonless reimplementation of udev, that is of
additional interest to us in Nixpkgs because (currently with a small
upstreamable build system patch) it's possible to build it statically,
which systemd's udev is unlikely to support in the near future[1].

In future, it might be good to default to using libudev-zero in
pkgsStatic, but for now let's just introduce the package, so people
doing static builds can at least use it themselves using overrides or
overlays.
