Subject: Fix systemd_ RPM macros usage on Debian-based distributions

Debian-based distributions do not seem to provide RPM macros for
dealing with systemd pre- and post- (un)install actions: this results
in errors when installing or upgrading .deb packages because the
resulting control scripts contain the following unresolved macros:

 * %systemd_post
 * %systemd_preun
 * %systemd_postun

Fix this by providing default values for postinstall, preuninstall and
postuninstall scripts when these macros are not defined.
