Subject: [PATCH] units: rework systemd-nspawn@.service unit

- Unescape instance name so that we can take almost anything as instance
  name.

- Introduce "machines.target" which consists of all enabled nspawns and
  can be used to start/stop them altogether

- Look for container directory using -M instead of harcoding the path in
  /var/lib/container
