perf python: Include rwsem.c in the pythong biding

We'll need it for the cgroup patches, and its better to have it in a
separate patch in case we need to later revert the cgroup patches.

I.e. without this we have:

  [root@...e ~]# perf test -v python
  19: 'import perf' in python                               :
  --- start ---
  test child forked, pid 148447
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: /tmp/build/perf/python/perf.cpython-37m-x86_64-linux-gnu.so: undefined symbol: down_write
  test child finished with -1
  ---- end ----
  'import perf' in python: FAILED!
  [root@...e ~]#
