tests/copperline: work around 68000/68010 hostfs boot hang - #101

[[filesys]] host-directory boot mounts hang forever on a 68000/68010 guest under released Copperline 0.12.0/0.13.0 (a 16-bit-bus move.l split never rings the hostfs MMIO doorbell). Root-caused and fixed upstream in CopperlineHQ/Copperline#312, not yet released, so run.sh/bench.sh keep their configs on real 68000 and gain a COPPERLINE= env var to point at a fixed local build instead of working around it by raising the CPU model (which would invalidate bench.sh's 68000 KDF-throughput numbers). Also fixes an unrelated pre-existing link error in bench.sh's docker build: hmac.c unconditionally defines the SHA-256/512 HMAC variants, so sha256.c/sha512.c need to be linked even though this benchmark only exercises SHA-1.
