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
72: dlfilter C API : Ok
[root@five ~]# perf test -v dlfilter
72: dlfilter C API :
