    Fix: "find" should run only in specific directories

    Some users reported that running find over "/var/lib" for cleanup
    purposes can take too long depending on what you have installed.
    A particular example was having "lxcfs" fuse mounted in /var/lib.
    That can make the search for cluster leftovers to take quite some
    time, making user to believe the process has hang.
