zipl: add ldipl-dump option

Browse Source 
CCW and LD-IPL records cannot be used at the same time for dumps because
CCW dump uses the standalone dumper, while LD-IPL uses ngdump. The first
one writes data to the raw disk without any filesystem, while the second
one uses an ext filesystem. Therefore we need a way to tell zipl which
kind of dumper it should install, as both cannot be installed at the
same time. The device given is the same for both types, so we cannot use
this to decide which type to install. Therefore add a '--ldipl-dump' option
so the user can decide which type of dump to use.
