[CRIU] [PATCH 1/2] python lib: rename rpc.py to rpc_pb2.py

[Tycho Andersen]

Unfortunately, newer versions of protobuf check that the file suffix ends
in _pb2.py:

sudo ./zdtm.py run -t zdtm/static/apparmor_stacking
Traceback (most recent call last):
  File "./zdtm.py", line 23, in <module>
    import criu as crpc
  File "/home/ubuntu/criu/test/criu.py", line 12, in <module>
    import rpc
  File "/home/ubuntu/criu/test/rpc.py", line 36, in <module>
    type=None),
  File "/usr/lib/python2.7/dist-packages/google/protobuf/descriptor.py", line 652, in __new__
    _message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors should not be created directly, but only retrieved from their parent.
