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 https://github.com/kubernetes/repo-infra/pull/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
NONE
```
