go.mod: remove replace and update github.com/gogo/googleapis v1.4.1

gogo/googleapis has a single dependency (github.com/gogo/protobuf), which is
currently the same version as we use, and we have a separate replace for that
dependency, so removing this override should not make a difference there.

gogo/googleapis v1.4.1 Includes updated protos with the gogo/protobuf fixes for
[CVE-2021-3121](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3121)
