76929ab51f kselftests/ftrace: Add hist trigger testcases 
Add the hist trigger testcases for ftracetest.
This checks the basic histogram trigger behaviors like as;
 - Histogram trigger itself
 - Histogram with string key
 - Histogram with compound keys
 - Histogram with sort key
 - Histogram trigger modifiers (execname, hex, syscall)
 - Multiple histograms on an event
 - Named histogram
 - Named histogram on multi events

Here is the test result.
