Summary: On AIX psutil can run into problems with permissions to read the process tree, which causes problems for python timeout tests which need to kill off a test and it's children. This patch adds a workaround by invoking shell via subprocess and using a platform specific option to ps to list all the descendant processes so we can kill them. We add some checks so lit can tell whether timeout tests are supported with out exposing whether we are utilizing the psutil implementation or the alternative.
