tracing/kprobes: Add selftest scripts testing kprobe-tracer as startup test
Add two selftest scripts which tests kprobe-tracer as the startup
selftest does.
These test cases are testing that the kprobe_event can accept a
kprobe event with $stack related arguments and a kretprobe event
with $retval argument.
