rebase to v0.9.7 (amend)
    
    subpackaging kpatch-dnf means that a new version of both kpatch and
    kpatch-dnf needs to be set for brew to accept the new package build.
    
    Augment the kpatch-dnf subpackage version by prefixing the kpatch
    version in order to satisfy brew in cases where only kpatch had its
    version bumped
