Give git user its own home, separate from /srv/git

authorized_keys lived under /srv/git (git's $HOME), the same tree
restic backs up and restores. backup couldn't even read it (0700,
unreadable by the backup user), and restore --delete treated it as
extraneous and deleted it, breaking push access after every restore.

git now gets a normal separate home; clone-prefix in cgitrc serves the
repos dir by absolute path instead of the ~-relative form, since that
relied on $HOME being the repos dir. Drops the sshd_config.d Include/
Match-block/AllowUsers approach tried first — it directly conflicted
with pve-lxc-ssh's sshd_config push, which fully overwrites the file
on every run and has no way to know about cgit's edits.
