    usr.sbin/makefs: Add offline HAMMER2IOC_VERSION_GET support
    
    The offline version get uses existing "-o V" option with no argument.
    `image-file` argument is a valid HAMMER2 image file or block device.
    `directory` argument is unused, but needs to be a valid path or "--".
    
    e.g.
    $ makefs -t hammer2 -o V /dev/adx --
    $ makefs -t hammer2 -o V /path/to/hammer2.img --
    
    There is no hammer2(8) directive for this as it's internally used.
