Subject: Ensure the default KBFS mount directoy is created on service start
References: https://github.com/keybase/kbfs/issues/1655
Upstream: never

This ensure that the default KBFS mount directory is create on service start.
Upstream does this using their `run_keybase` script which is not included in
this package.

This solution is much cleaner than upstreams. However, we cannot directly
upstream it due to the hack for Leap 15.0. In addition, upstream probably
wouldn't like the Systemd 235 requirement.
