Subject: [PATCH] tests: kill process group on failure

Test suite is often leaving `stray` processes on failure. They are
harmless, but may cause future test runs fail because those `stray`
processes are occupying `common.PORT` or due to some other reasons.

Killing whole process group on test suite failure should help in such
cases.
