http2: skip "write: broken pipe" failures in TestServer on OpenBSD

This failure mode has been observed on openbsd/mips64 and openbsd/arm64. I have not diagnosed the precise root cause, but I suspect a platform bug — perhaps a bad interaction with the relatively weakly-ordered memory models on these CPUs. For golang/go#52208.
