In 5b3b2d80f4 we dropped dbus as a build
dependency, however we still need it when building with systemd so
that the service directory is available via pkg-config.
In addition we can drop --with-dbus-datadir by unconditionally
requiring dbus as the datadir will then be fetched from pkg-config.
Fixes:
checking D-Bus bus services directory... configure: error: D-Bus bus services directory is required
