Add the benchmark testcase "kprobe-multi-all", which will hook all the kernel functions during the testing.
This series is separated out from [1].
Changes since V2: * add some comment to attach_ksyms_all, which notes that don't run the testing on a debug kernel
Changes since V1: * introduce trace_blacklist instead of copy-pasting strcmp in the 2nd patch * use fprintf() instead of printf() in 3rd patch
