Adrian Hunter 9f9c9a8de2 perf tests: Add dlfilter test
Add a perf test to test the dlfilter C API.

A perf.data file is synthesized and then processed by perf script with a
dlfilter named dlfilter-test-api-v0.so. Also a C file is compiled to
provide a dso to match the synthesized perf.data file.

Committer testing:

  [root@five ~]# perf test dlfilter
