onpanic: add support for multipathed zfcp-attached SCSI disks

Depends on https://build.opensuse.org/package/show/Base:System/s390-tools
commit ("mkdump: add support for multipathed zfcp-attached SCSI disks")
from SUSE bug 1216257.

Users should use multipathing for all zfcp-attached SCSI disks.
Since a long time, zipl can write the partition-based zfcpdump
standalone dumper boot record to a multipath device.
This avoids users having to flush multipath maps or maintain
a multipath exception list just for zfcp dump volumes.
Always having multipathing for everything also provides redundant
access to the dump volume on importing the dump from the volume into
a filesystem after the standalone dumper had written the dump.

An updated mkdump.pl from SUSE s390-tools understands and lists such
multipath devices. Make "yast onpanic" understand /dev/mapper/... multipath
devices as better alternative to single path SCSI disks /dev/sd[a-z]+.

Fixes SUSE bug 1020336.
