perf python: Add missing files to binding link list

Fixing this problem, introduced recently:

  $ perf test python
  16: Try 'import perf' in python, checking link problems      : FAILED!

In verbose mode we find out what is missing:

  $ perf test -v python
  16: Try 'import perf' in python, checking link problems      :
  --- start ---
  test child forked, pid 24894
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: /tmp/build/perf/python/perf.so: undefined symbol: find_next_bit
  test child finished with -1
  ---- end ----
  Try 'import perf' in python, checking link problems: FAILED!
