Changes from v8:
Found and fixed a bug in the selftests that check the README file.
I was testing that requirement with eprobes, and found that it was not
flagging it as not added. Found the reason, and fixed it.
Changed the selftest for add/remove of the eprobe to just add test
and remove it.
Moved the selftest that added a eprobe to a synthetic event into the trigger
tests.
Have the "testing duplicate" not test kprobes if kprobes are not configured
in.
