os: invoke processKiller synchronously in testKillProcess

Browse Source 
Previously, testKillProcess needlessly invoked processKiller in a
separate goroutine and failed to wait for that goroutine to complete,
causing the calls to t.Fatalf in that goroutine to potentially occur
after the test function had already returned.

Fixes #43722
