perf tools: Fix build error due to zfree() cast

It failed to build perf on my ubuntu 10.04 box (gcc 4.4.3):

    CC       util/strlist.o
  cc1: warnings being treated as errors
  util/strlist.c: In function ‘str_node__delete’:

    CC       util/strfilter.o
  make: *** [util/strlist.o] Error 1

  util/srcline.c:143: error: dereferencing type-punned pointer will break strict-aliasing rules
  make: *** [util/srcline.o] Error 1

It seems it only allows to remove 'const' qualifier.
