Subject: [PATCH v1] kprobes: unused header files removed

As kernel test robot reported, lib/test_objpool.c (trace:probes/for-next)
has linux/version.h included, but version.h is not used at all. Then more
unused headers are found in test_objpool.c and rethook.c, and all of them
should be removed.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202310191512.vvypKU5Z-lkp@intel.com/
