zconf/lsdasd: add Copy Pair output option

Browse Source 
Add an option -P|--copy-pairs to show all DASD devices with copy
relations set up in the system and their roles.

The output looks like:

    # ./s390-tools/zconf/lsdasd -h
    [...]
            -P|--copy-pairs
	             Print information about copy pairs.

     # ./s390-tools/zconf/lsdasd -P
     Bus-ID    Role       Name      Paired devices
