* add go module support, update go-bindata ref, bump runc dep
```
go mod init github.com/google/cadvisor
go mod tidy
go get github.com/matttproud/golang_protobuf_extensions@c182affec369e30f25d3eb8cd8a478dee585ae7d
go get github.com/containerd/typeurl@5eb25027c9fdd675e1db2bd25af02f5db75027ab
```
Somehow the dependencies retrieved by `go mod init` was mismatched (maybe because
runc itself does not support go module yet ?). This fixes the dependencies retrieved
in go module, the packages bump itself seems sane.
The original go-bindata is unmaintained and is on an old revision, so our usage
of it is outdated. Changed to https://github.com/kevinburke/go-bindata which
seems to be a more official and well maintained fork, and bump to latest version.
