    dropbear: use ssh-keygen  as an alias for dropbearkey
    
    The DropBear's dropbearkey supports limited set of arguments of
    OpenSSH ssh-keygen:  -t, -q -N -Y
    After the change you can generate a key with the same command.
    Still many features of the original OpenSSH ssh-keygen are absent in
    the dropbearkey.
    If it's needed then users should install openssh-keygen package that
    will replace the /usr/bin/ssh-keygen with the full version.
