man: add libsystemd(3)
Before libsystemd-daemon, libsystemd-journal, libsystemd-id128, etc., were merged into libsystemd, it was enough to have individual man pages for them. But they have been delivered as one thing for many years, so it's better to have a landing page for libsystemd. It mostly directs to individual pages anyway.
