This is needed so we can build the runc shim without grpc as a
transative dependency.
With this change the runc shim binary went from 14MB to 11MB.
The RSS from an idle shim went from about 17MB to 14MB (back around
where it was in in 1.7).

Allow the api to stay at the same v1 go package name and keep using a
1.x version number. This indicates the API is still at 1.x and allows
sharing proto types with containerd 1.6 and 1.7 releases.
