fix(nixos/git-server): Correctly enable the git config feature of gitolite

The previously set variable is only used in the gitolite.conf file for
the `config` specifications on each repo. We can't use that because we
use "wild-repos". Thus we need to add the `user-configs` option to each
repo, allow users to change the git settings specified there with a
simple `ssh git@git.vhack.eu config <repo> --set cgit.owner <name>`.
