perf annotate: Mark jump instructions with no offset
I.e. jumps that go to code outside the current function, that is denoted
in objdump -dS as:
399f877a9f: jne 399f87bcf4 <_L_lock_5154>
I.e. without the + after the name of the current function, like in:
399f877aa5: jmp 399f877ab2 <_int_free+0x412>
The browser will use that info to avoid drawing connectors to the start
of the function, since ops.target.addr was zero.
