perf test: Fixup aliases checking in the 'vmlinux matches kallsyms' test

There are cases where looking at just the next and prev entries is not
enough, like with:

  $ readelf -sW /usr/lib/debug/lib/modules/4.3.3-301.fc23.x86_64/vmlinux | grep ffffffff81065ec0
   4979: ffffffff81065ec0 53 FUNC  LOCAL  DEFAULT 1 try_to_free_pud_page
   4980: ffffffff81065ec0 53 FUNC  LOCAL  DEFAULT 1 try_to_free_pte_page
   4981: ffffffff81065ec0 53 FUNC  LOCAL  DEFAULT 1 try_to_free_pmd_page

So just search by name to see if the symbol is in kallsyms.
