runtime: enable race detector on openbsd/amd64

Browse Source 
Now that this commit[1] has landed in LLVM the .syso file can be generated for
OpenBSD.

With the changes to src/runtime running the sample race[2] detects the data
race as expected.

Based on golang/go#39464 (https://go-review.googlesource.com/c/go/+/237057) from
Aaron Bieber <deftly@gmail.com>, however the race_openbsd_amd64.syso file has
been built on OpenBSD 6.4 and necessary changes added to race.bash.
