Some projects unset GOOS and GOARCH before running `go run` in order to
force the build host. Giving the wrapper using `GOFLAGS="-exec=..."`
breaks this because that expects the target host. `go run` can also find
the wrapper in the PATH as `go_${GOOS}_${GOARCH}_exec`, so take this
more targetted approach instead.
