Docker: Fix git sshd

This was completely bugged out. This commit fixes git, provides
two separate cgit servers for the different URL bases and also
supplies a smartgit service for $AURWEB_URL/repo.git interaction.

Docker image needs to be rebuilt with this change:

    $ docker build -t aurweb:latest .
