Josh Poimboeuf da4326573a objtool/klp: Fix kCFI trap handling
.kcfi_traps contains references to kCFI trap instruction locations.
When a KCFI type check fails at an indirect call, the trap handler looks
up the faulting address in this section.

Add it to the special sections list so the entries get extracted for the
changed functions they reference.
