Subject: [PATCH] Make build.sh work for windows plugins.

When building the windows plugin exe's (host-local, flannel, win-overlay, win-bridge),
it was necessary to use 'GOOS=windows go build path/to/plugin' rather than the build script.

This makes 'GOOS=windows GOARCH=amd64 ./build.sh' build all the windows plugin binaries.
