selftests: ftrace: Add a selftest to test event enable/disable func trigger
This adds a test to enable and disable trace events via the function
triggers. It tests enabling and disabling the sched:sched_switch event via
the the event_enable and event_disable function triggers attached to the
schedule() kernel function.
The test does the following:
o disable all events
o disables or enables the sched_switch event
o writes schedule:event_enable/disable:sched:sched_switch into set_ftrace_filter
o 5 times it checks to make sure:
. Writes 0/1 into the sched_switch/enable
. Checks that the sched_switch/enable goes back to 1/0
o Resets the events
o writes schedule:event_enable/disable:sched:sched_switch:3 into set_ftrace_filter
o Does a loop of 3 to see that sched_switch/enable file gets updated
o Makes sure the sched_switch/enable stops getting updated
