Server: Debian package bug fix: Include /usr/lib/tmpfiles.d dir

The Debian package for the server needs the /usr/lib/tmpfiles.d
directory in its .dirs file in order for the directory to exist when
the Makefile "install-server" rule is run, otherwise the
tmpfiles.d-mandos.conf file will not be installed.

* debian/mandos.dirs (usr/lib/tmpfiles.d): Added.
