Drop installation-time dependencies on dracut and kmod
    
    rdma-core provides a plugin for dracut, but does not "use" dracut.
    
    It seems that the dependencies on dracut and kmod were added because
    of directory ownership
    (https://bugzilla.redhat.com/show_bug.cgi?id=1404043#c8). Let's co-own
    the directories instead. Pulling in such a big package as dracut along
    with dependencies just for the directory is not very nice.
    
    Dracut by itself is 1MB, and pulls in bash, coreutils, grep (which
    means also libpcre), procps-ng, systemd, and a bunch of libraries.
