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.
  ----
  # ./ftracetest test.d/trigger/*hist*.tc
  === Ftrace unit tests ===
  [1] event trigger - test histogram modifiers    [PASS]
  [2] event trigger - test histogram trigger      [PASS]
  [3] event trigger - test multiple histogram triggers    [PASS]

  # of passed:  3
  # of failed:  0
  # of unresolved:  0
  # of untested:  0
  # of unsupported:  0
  # of xfailed:  0
  # of undefined(test bug):  0
