Bump rules_go and build "static" binaries in pure Go mode

**What this PR does / why we need it**: uses latest set of enhancements in bazelbuild/rules_go to properly build the "static" Go binaries using pure Go (i.e. `CGO_ENABLED=0`), and to support cross compilation of these binaries. Cross compilation of cgo-enabled binaries is still not supported.

Also depends on kubernetes/repo-infra#52, and requires bazel 0.8+ (which is not yet enabled in CI for kubernetes/kubernetes).

Note that for proper cross compilation we'll also need to remove the hardcoded "linux-amd64" that's strewn about several `BUILD` files.

**Release note**:

```release-note
