Make flaky tests less flaky

[RebeccaMahany]

Autoupdate tests:

• Looks like this one just needed more time to run 🤞

Rungroup tests:

• Not sure what's up here yet, so I'm capturing the logs from rungroup and printing them on error, so we can figure out why we sometimes don't see all of the rungroup actors interrupt successfully

Osquery tests:

• Standardize waitHealthy to wait for the osquery instance to become healthy for as long as we actually wait (1 min for the socket file to be created, 10 seconds for the socket file to become available)
