[PATCH] perf: fix undefined symbols in python binding

[Ben Noordhuis]

Add dummy test_attr__enabled and test_attr__open symbols to
util/python.c to fix the following dynamic linker error:

  $ python python/twatch.py
  Traceback (most recent call last):
    File "python/twatch.py", line 16, in <module>
      import perf
  ImportError: /path/to/perf.so: undefined symbol: test_attr__enabled
