tests: run system tests also with monitor-all=true

Before this patch, each system test was supposed to run four times:
- with and without northd-parallelization
- with and without monitor-all
However, while the titles of the test were updated, system tests were never
run with monitor-all=true (i.e. they were run twice w/o monitor-all).

This is now fixed, and the four flavors of the tests are run.
