perf test: Replace data symbol test workload with datasym

So that it can get rid of requirement of a compiler.

  $ sudo ./perf test -v 109
  109: Test data symbol                                                :
  --- start ---
  test child forked, pid 844526
  Recording workload...
  [ perf record: Woken up 2 times to write data ]
  [ perf record: Captured and wrote 0.354 MB /tmp/__perf_test.perf.data.GFeZO (4847 samples) ]
  Cleaning up files...
  test child finished with 0
  ---- end ----
  Test data symbol: Ok
