Restore compatibility with F40
    
    In systemd upstream CI, we only have the rawhide branch, because we import
    dist-git via git submodule. But we want to build systemd on F40 too from this
    branch, so conditionally ressurect the patch to make that work. This partially
    reverts 69d6e4469589ae42c044383cd0173572f64b20fb.
