selftest: Add test of NDR marshalling from python, starting with wbint

These patches are to address an issue unpacking a very large
winbind.wbint_Principals array (100,000).

We need the NDR_TOKEN_MAX_LIST_SIZE value exposed as
otherwise a well-meaning incrase of this value would
invalidate the test.
