Christian Hesse aeffec60f6 MDEV-19210: do not run pre and post scripts as root
Now that we do not pollute systemd's environment but write private
environment files running these as root is not longer required. So
let's drop `PermissionsStartOnly=true`.

Debian adds extra `ExecStartPre=` and `ExecStartPost=`, though.
Use special executable prefix for full privileges there. (See
systemd.service(5) for details.)
