Subject: [PATCH] fix: store each s8k_cpu.zip member once

ROM_START(s8k_cpu) in src/devices/bus/zbi/s8k_cpu.cpp (mamedev f34f0250) names cpu_34-0715-03a.u76, cpu_34-0717-03a.u75 and cpu_34-0718-03a.u77 under two system BIOSes with the same CRC. The archive held them twice. Rebuilt with build_torrentzip from the 13 distinct members, each checked against the mame0289 recipe sha1.
