test: properly kill journalctl

Browse source 
sudo journalctl -af -n 1 -u "${WORKER_UNIT}" &
WORKER_JOURNAL_PID=$!

In this snippet, WORKER_JOURNAL_PID is set to the PID of the sudo process.
Sudo doesn't propagate any signals - therefore the child process of sudo
(journalctl in this case) isn't killed when a signal is sent to the parent.

Use pkill -P instead which kills all processes where sudo is the parent.
