zipl/boot: Set the new version in the dumper and in the dump header

Browse Source 
Since we are using the existing s390 extended dump format for compressed
dumps as well, set the version of the s390_ext dumper with compression
support and also dump header of the compressed dump to '2' (in order for
zgetdump to distinguish).
