[apparmor] [patch 2/5] tests: check for early task exit in onexec tests

[steve at nxnw.org]

Based on a patch by John Johansen <john.johansen at canonical.com>

(I converted the check to look for the process directory in /proc
rather than sending signal 0 to the task, as John had done in a patch
sent to me, to prevent failures in signal delivery from blocking the
check from working correctly.)
