tracing: Have function_graph selftest call cond_resched()
When all kernel debugging is enabled (lockdep, KSAN, etc), the function
graph enabling and disabling can take several seconds to complete. The
function_graph selftest enables and disables function graph tracing
several times. With full debugging enabled, the soft lockup watchdog was
triggering because the selftest was running without ever scheduling.
Add cond_resched() throughout the test to make sure it does not trigger
the soft lockup detector.
