Peng Tao 0e2be42514 vendor: fix containerd/cgroups dependency
Gopkg.lock says it's "dbea6f2bd41658b84b00417ceefa416b979cbf10"
but it is actually "5017d4e9a9cf2d4381db99eacd9baf84b95bfb14".

We need to make sure Gopkg.lock does not lie otherwise `dep ensure`
would really fetch the locked revision and it causes build failure
due to API changes.

Introduced by: 76d9db3e0b (vendor: Add github.com/gogo/protobuf).

While at it, constraint containerd/cgroups to a working revision.

Fixes: #1447
