Use libsystemd instead of libsystemd-daemon

In systemd v209, released in 2014, 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.
