cgroup: Respect DefaultMemoryMin when setting memory.min
    
    This is an oversight from https://github.com/systemd/systemd/pull/12332.
    
    Sadly the tests didn't catch it since it requires a real cgroup
    hierarchy to see, and it wasn't seen in prod since we're only currently
    using DefaultMemoryLow, not DefaultMemoryMin. :-(
    
    (cherry picked from commit 64fe532e90b3e99bf7821ded8a1107c239099e40)
