cmd/racebuild: add darwin/arm64 support
In Go 1.16 we added darwin/arm64 (macOS) port, along with race
detector support. At that time we didn't have a builder, so the
syso file was built manually. Now that we have a builder, this CL
adds darwin/arm64 support to racebuild, so the syso file can be
built with it.
Verified that it successfully builds the syso and it passes the
tests.
