Created an attachment (id=3850)

Updated patch
Changed to the old one.
1. Once build-id check finished, early return
2. Trigger warning if build-id doesn't match and make finder.callback return.
3. build-id checking limited to map_p in vma.callback
4. Use module path to compare vm_path. (thanks to Mark Wielaard)
Did some tests on FC10. Looks fine.
Need to be improve:
1. Still need to hook stap_uprobe_process_found explicitly for an EXEC
finder.callback since vma.callback == NULL.
2. The annoying problem is that the validation procedure will be repeated
many times. That depends on callbacks.
Any idea?
