* dbus/dbus-sysdeps-unix.c:
(_dbus_get_standard_system_servicedirs):
* dbus/dbus-sysdeps-win.c:
Provide a way to get the standard system servicedirs, just like we do
for the session service dirs. These should be seporate, as there may
be a security issue starting up some session stuff as root.
The use-case for the same binary starting up per-system _and_
per-session is also not valid.
