perf python: Fix argument name list of read_on_cpu()

Browse source 
Mandatory arguments need to be present in the argument name list, as
well as optional arguments, otherwise python barfs:

	# ./python/twatch.py
	Traceback (most recent call last):
	  File "./python/twatch.py", line 41, in <module>
	    main()
	  File "./python/twatch.py", line 32, in main
	    event = evlist.read_on_cpu(cpu)
	RuntimeError: more argument specifiers than keyword list entries

Hence, add cpu to the name list.
