Use a separate linker script eckd2dump_sv.lds for single volume dumper with compression support. The new dump tool with zlib compression support now has a size of 8 pages. Since DASD stand alone dump requires a block size of 4K, we are not affected by the stage 2 size limitations and can load the dumper to stage 2 as before. We just need to move the HEAP section for ECKD dumper in the layout definitions up to 0xb000 address. Also expand the stack by unused 0x400 bytes.
