ftrace: give time for wakeup test to run



It is possible that the testing thread in the ftrace wakeup test does not
run before we stop the trace. This will cause the trace to fail since nothing
will be in the buffers.

This patch adds a small wait in the wakeup test to allow for the woken task
to run and be traced.
