Update lib/pq to fix cert permissions issues (#1804)

When attempting to connect to a PostgreSQL database using certificate
credentials, authentication may fail due to permissions issues on the
certificate files. When using Athens in Kubernetes, this issue may be
unavoidable when using secrets.

The github.com/lib/pq library has resolved this issue as of v1.10.6, so
this commit updates that library to the latest release version (v1.10.7)
to resolve the issue in Athens.
