Add a hackish attempt at a workaround for #961235
    
    Add a patch to create /run/user/0 if we're trying to resolve a
    DIR: ccache somewhere below it and neither the target location
    nor /run/user/0 exist yet.
    The better workaround is to set the location's owner to "linger"
    via logind, since even after we do what we're doing here, if
    the user logs in and logs back out, our location is still removed.
