    Make copying and moving swap depend on mkswap availability (#775932)
    
    Attempting to copy or move linux-swap partition was possible when the
    mkswap command was unavailable.  However as linux-swap is re-created as
    part of these operations the mkswap command is a mandatory requirement.
    Example copy operation results:
    
        Copy /dev/sdb1 to /dev/sdb2
        + calibrate /dev/sdb1
        + check file system on /dev/sdb1 for errors and (if possible) fix them
        + create empty partition
        + set partition type on /dev/sdb2
        + copy file system from /dev/sdb1 to /dev/sdb2           [SUCCESS]
            Partition copy action skipped because linux-swap file system does not contain data
        + grow file system to fill the partition                 [WARNING]
            growing is not available for this file system
    
    Because mkswap was not available the grow action didn't re-create
    the linux-swap so the newly copied partition is left without any content
    and therefore reported as an unknown partition.
    
    Fix by making copying and moving linux-swap depend on mkswap being
    available.
