perf annotate: Add "_local" to jump/offset validation routines

Because they all really check if we can access data structures/visual
constructs where a "jump" instruction targets code in the same function,
i.e. things like:

  __pthread_mutex_lock  /usr/lib64/libpthread-2.26.so
  1.95 │       mov    __pthread_force_elision,%ecx
       │    ┌──test   %ecx,%ecx
  0.07 │    ├──je     60
       │    │  test   $0x300,%esi
       │    │↓ jne    60
       │    │  or     $0x100,%esi
       │    │  mov    %esi,0x10(%rdi)
       │ 42:│  mov    %esi,%edx
       │    │  lea    0x16(%r8),%rsi
       │    │  mov    %r8,%rdi
       │    │  and    $0x80,%edx
       │    │  add    $0x8,%rsp
       │    │→ jmpq   __lll_lock_elision
       │    │  nop
  0.29 │ 60:└─→and    $0x80,%esi
  0.07 │       mov    $0x1,%edi
  0.29 │       xor    %eax,%eax
  2.53 │       lock   cmpxchg %edi,(%r8)

And not things like that "jmpq __lll_lock_elision", that instead should behave
like a "call" instruction and "jump" to the disassembly of "___lll_lock_elision".
