Enabling modules from runtime.TestLldbPython: #30751. But none of the builders failed. This issue is to figure out why, and ensure that some builder is running that test going forward. The problem may be that we need to run /usr/sbin/DevToolsSecurity -enable on the macOS builders; see discussion at #30751.
Apparently Josh's intuition in CL 170339 was correct. We do need sudo.
Sometimes. It's weird. It works without sudo with gomote, but not
during start-up. The environment is slightly different.
In any case, sudo works. Verified on macOS 10.10, 10.11, 10.12, and 10.14.
