treewide: remove wkennington as maintainer
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.

# This test runs a Bittorrent tracker on one machine, and verifies
# that two client machines can download the torrent using
# `transmission'. The first client (behind a NAT router) downloads
# from the initial seeder running on the tracker. Then we kill the
# initial seeder. The second client downloads from the first client,
# which only works if the first client successfully uses the UPnP-IGD
# protocol to poke a hole in the NAT.
