Update apache/thrift to 0.11.0 and remove pinning (#1317)

The `apache/thrift` recently released a new version of `0.11.0`
several days ago. This release is compatible with other packages
and as such, there is no need to pinning the `apache/thrift`
to `master` anymore in Gopkg.toml.

This fix removes the pinning of `apache/thrift` in Gopkg.toml,
and updates all dependencies of coredns.
