perf annotate browser: Suppress the callq address 

0.00 |       callq  ffffffff8112f190 <__mod_zone_page_state>

Becomes:

    0.00 |       callq  __mod_zone_page_state

But if you press 'o' it gets verbose, i.e. as in objdump -dS:

    0.00 | ffffffff8116bdda:  callq  ffffffff8112f190 <__mod_zone_page_state>
