perf dso: Fix build when libunwind is enabled

Browse Source 
Now that symsrc_filename is always accessed through an accessor, we also
need a free() function for it to avoid the following compilation error:

  util/unwind-libunwind-local.c:416:12: error: lvalue required as unary
    ‘&’ operand
  416 |      zfree(&dso__symsrc_filename(dso));
