test: use pkg-config to get user unit dir when installing dbus user socket

Usually on Debian ROOTLIBDIR is /lib/<arch triplet>, which is not the right place.
Use pkg-config since we define it, and then fallback to /usr/lib/systemd/user which is
the canonical location.
On both Debian&friends and Fedora dbus/dbus-broker install the user socket/service
under /usr/lib/systemd/user, not /lib/systemd/systemd/user.
