[PATCH] enable build support without systemd compatibility libraries

[Umut Tezduyar Lindskog]

systemd 209 merged all the libraries to libsystemd. Old
libraries can still be enabled with --enable-compat-libs
switch in systemd but this increases the binary size.

Implement a fallback library check in case compat libraries
dont exist.
