[IronPython] pickling python types

[Ronnie Maor]

Just a clarification - the GetPythonType below is superfluous
pickle.dumps(Int64) fails the same way

seems that all python types that aren't native (i.e. shadow an existing CLR
type) fail that way.
Pickling the CLR type (RuntimeType) actually works.
