TestKit backend: run python with unbuffered stdout/err (#817)

robsdedude · web-flow · commit f1795de2495b · 2022-10-07T16:15:23.000+02:00
Test TestKit backend gets killed forcefully (`SIGKILL`) by TestKit/docker.
Therefore, buffered stdout/stderr (default Python interpreter behavior) can lead
to the last bits of output missing in the log files.
