perf symbol: Fix symbol parsing in certain cases: use the build-id as a symlink
In some cases distros have binaries and debuginfo in weird places:
[root@doppio tuna]# ls -la /usr/lib64/{xulrunner-1.9.1/xulrunner-stub,firefox-3.5.2/firefox}

Seemingly we don't have a .symtab when we actually can find it
if we use the .note.gnu.build-id ELF section put in place by
some distros. Use it and find the symbols we need.
