Subject: [PATCH] build.h: include default cgroup hierarchy setting in
 --version output

This is pretty important, and we print this string during startup, so putting
the default hierarchy information might help with diagnosis if things go awry.

$ ./systemctl --version
elogind 232

v2: make the message nicer by including the ./configure option argument
directly in output
