mount_digiparts.sh: add unit running check for systemd devices 

For devices running 'systemd', the mount process is done through 'systemd-mount', which
spawns a system unit. Trying to mount the partition again throws an error stating that a
unit with the same name is already running. To avoid it, check if the unit is already
spawned before mounting the partition and, if so, just restart the unit.
