zdump: Drop support of non-extended single volume DASD dumpers

Browse Source 
Since DASD standalone dumper does not support non-extended s390 dump
format for years, drop zgetdump support of non-extended s390 single volume
DASD dump-tool:
- Merge dt_390sv_ext.c and dt_s390sv.c counterparts.
- Update DT vector of supported dump tools removing dt_s390sv entry and
  keeping dt_s390sv_ext entry for s390 single volume extended dump tool.
- Remove dt_s390sv.c source and update the Makefile accordingly.
- Remove magic constants relevant to non-extended s390 single volume DASD
  dumper.
- Drop s390 single volume DASD dumper version 5 in df_s390_dumper_read().

Note: We still need support of non-extended s390 dump format since such
output dump files can be produced by 'zgetdump -f s390' via dfo_s390. Thus,
both dfi_s390 and dfi_s390_ext DFI vector entries remain in order to
process s390 dumps files as well as s390_ext dumps on the DASD partition.
