XFCE: allow to set a specific release to be used while grabbing the source

This will be used to avoid duplicated code in many XFCE related
recipes. Without that, all recipes that uses a different version then
the global XFCE release need to specify the SRC_URI making harder to
update and change the mirror to be used globaly.
