Add a testcase to test kprobes via ftrace interface with many concurrent kprobe events. This tries to add many kprobe events (up to 256) on kernel functions. To avoid making ftrace-based kprobes (kprobes on fentry), it skips first N bytes (on x86 N=5, on ppc or arm N=4) of function entry. After that, it enables all those events, disable it, and remove it. Since the unoptimization buffer reclaiming will be delayed, after removing events, it will wait enough time.
