Server: Make persistent state directory mode u=rwx,go=

The Makefile target "install-server" creates the server persistent
state directory /var/lib/mandos as mode u=rwx,go= (0700).  Make this
also the case for the Debian package (unless overridden by
dpkg-statoverride).

* debian/mandos.postinst (configure): Fix state directory permissions,
  but only if not listed by "dpkg-statoverride".
