Fall back to /var/run for pidfile if /run is not a directory.
This is for old (possibly non-Debian) systems which have not migrated
from /var/run to /run yet.
* init.d-mandos (PIDFILE): Fall back to /var/run/mandos.pid if /run is
not a directory.
* mandos (pidfilename): - '' -
* mandos.xml (FILES): Document fallback to /var/run/mandos.pid if /run
is not a directory.
