Subject: Fix JobControl tests for open source.

ioctl calls with TIOCSCTTY fail if the calling process already has a
controlling terminal, which occurs on a 5.4 kernel like our Ubuntu 18 CI.
Thus, run tests calling ioctl TTOCSCTTY in clean subprocess.

Also, while we're here, switch out non-inclusive master/slave for main/replica.
