perf python: Remove dependency on 'machine' methods

The python binding still doesn't provide symbol resolving facilities,
but the recent addition of the trace_event__register_resolver() function
made it add as a dependency the machine__resolve_kernel_addr() method,
that in turn drags all the symbol resolving code.

The problem:

  [root@zoo ~]# perf test -v python
  17: Try 'import perf' in python, checking link problems      :
  --- start ---
  test child forked, pid 6853
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: /tmp/build/perf/python/perf.so: undefined symbol: machine__resolve_kernel_addr
  test child finished with -1
  ---- end ----
  Try 'import perf' in python, checking link problems: FAILED!
  [root@zoo ~]#

Fix it by requiring this function to receive the resolver as a
parameter, just like pevent_register_function_resolver(), i.e. do
not explicitely refer to an object file not included in
tools/perf/util/python-ext-sources.

  [root@zoo ~]# perf test python
  17: Try 'import perf' in python, checking link problems      : Ok
  [root@zoo ~]#
