ftracetest: Use proper logic to find process PID
Half of the test in instance-event.tc was updated to use $! to find the PID of the previous background process that was launched, but the second part of the test still used the parsing of "jobs", which does not work on all shells like $! does. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
