Hi!

In systemd v209, released over a year ago, the various libsystemd-* libraries
(libsystemd-journal.so, libsystemd-login.so, libsystem-daemon.so,
libsystemd-id128.so) were merged into a single libsystemd.so library to reduce
code duplication and avoid cyclic dependencies [1].

The attached patch tries to keep the changes minimal, and simply checks for libsystemd first and then falls back to the old libsystemd-journal name.
This way, realmd can be still be built with systemd < 209.


I intentionally did not rename the name of the configure switch.
If you prefer that and/or only want to check for the new libsystemd.pc, please let me know and I'll update the patch accordingly.
