Disable flaky Driver/lock_interface.swift test to keep CI reliable.

[kavon]

This Driver/lock_interface.swift test has been spontaneously failing for the past few days. I've decided to disable it until an investigation and fix can happen. This test failed at least once a few days earlier.

Here is an example failure from a recent build:
