Missing CAN_RAW check in Python 3.3.3

Python 3.3.3 assumes that if AF_CAN is defined then CAN_RAW is defined as well.

It won't assemble with old kernels. 

Either an additional check for CAN_RAW should be applied in the configuration script or Python 3.3.3 dependence on the newest kernels should be made mandatory
(configure check). It could be back to normal if a CAN_RAW check is applied and the problematic part of code is excluded. 

Python 3.3.3 can work with sockets without full CAN support but it won't.
