Move to golang version 1.10.4 -- the oldest stable golang release at the
time of writing -- since golang 1.10+ is needed to make namespace
handling safe.
Re-ordered a couple of structs (moved `sync.WaitGroup` fields) to keep
the `maligned` linter happy. Previously:
``
virtcontainers/pkg/mock/cc_proxy_mock.go:24:18⚠️ struct of size 160 could be 152 (maligned)
virtcontainers/monitor.go:15:14⚠️ struct of size 80 could be 72 (maligned)
```

Also bumped `languages.golang.meta.newest-version` to golang version
1.11, which is the newest stable release at the time of writing.
Fixes#148.
