CONFIG_KPROBES_ON_FTRACE is required for test-kprobe. Skip test-kprobe
when CONFIG_KPROBES_ON_FTRACE is not set. Since some kernel may not have
/proc/config.gz, grep for kprobe_ftrace_ops from /proc/kallsyms to check
whether CONFIG_KPROBES_ON_FTRACE is enabled.

selftests: livepatch: test livepatching a kprobed function
The test proves that a function that is being kprobed and uses a
post_handler cannot be livepatched.
Only one ftrace_ops with FTRACE_OPS_FL_IPMODIFY set may be registered
to any given function at a time.
Note that the conflicting kprobe could not be created using the
tracefs interface, see Documentation/trace/kprobetrace.rst.
This interface uses only the pre_handler(), see alloc_trace_kprobe().
But FTRACE_OPS_FL_IPMODIFY is used only when the kprobe is using a
post_handler, see arm_kprobe_ftrace().
