Trace Process.killProcessGroup calls in server/am/ to make it easier to find boot time regressions like 21813611 and 21861473. Process.killProcessGroup is a blocking call and usually takes about 50ms to finish on a recent device even when the process group contains only one process. Since Process.killProcessGroup tends to be called in a loop, the function can be a bottleneck. Bug: 21813611 Change-Id: I9c1727c0c0b321a30c96321198cc02f438496ded
