[PATCH v3] perf probe: fix kretprobe issue caused by GCC bug

Perf failed to add kretprobe event with debuginfo of vmlinux which is compiled by gcc with -fpatchable-function-entry option enabled. The same issue with kernel module. Issue: # perf probe -v 'kernel_clone%return $retval' .. Writing event: r:probe/kernel_clone__return _text+599624
