Set status.showUntrackedFiles to "no"

Each time the yadm repository is initialized or cloned,
set `status.showUntrackedFiles` to "no". This prevents untracked files
and directories from showing up in status commands. This seems to be the
most sensible default, because usually there will be MANY untracked
files in a user's $HOME directory.
