Namhyung Kim c9cd0c7e52 perf test: Add python JIT dump test 
Add a test case for the python interpreter like below so that we can
make sure it won't break again.  To validate the effect of build-ID
generation, it adds and removes the JIT'ed DSOs to/from the build-ID
cache for the test.

  $ perf test -vv jitdump
   84: python profiling with jitdump:
  --- start ---
  test child forked, pid 214316
  Run python with -Xperf_jit
  [ perf record: Woken up 5 times to write data ]
  [ perf record: Captured and wrote 1.180 MB /tmp/__perf_test.perf.data.XbqZNm (140 samples) ]
  Generate JIT-ed DSOs using perf inject
  Add JIT-ed DSOs to the build-ID cache
  Check the symbol containing the script name
  Found 108 matching lines
  Remove JIT-ed DSOs from the build-ID cache
  ---- end(0) ----
   84: python profiling with jitdump                                   : Ok
