versions: Remove golangci-lint and gometalinter entries

Removed the `golangci-lint` and `gometalinter` entries from the versions database:

- The `golangci-lint` package is now tracked in the `tests` versions database:

  https://github.com/kata-containers/tests/blob/master/versions.yaml

- The `gometalinter` package is no longer used.

See:

- kata-containers/tests#1323
- kata-containers/tests@d676140

Fixes: #2636.
