tmpfiles: add support for the new X line type

tmpfiles now has a new line type, X, which is similar to the x line type
used by the cleanup function.
This is not supported yet by OpenRc, because we do not have the cleanup
function in tmpfiles.sh, so I have added a dummy procedure for it so
we don't get complaints about this line type.
