Add --no-compress option to explicitly omit compression for single-volume
DASD dumper. Used primarily for test purposes.
Since only the lowest byte of mvdump_force field (struct
stage2dump_parm_tail) has been used, split it in two byte fields and use
one for the new no_compress attribute.
Update zipl help and zipl man page with the new parameter info.
