test/test_builtin.py: run most of test_type_name

The remaining failures are due to what appears to be a fundamental
difference between how RustPython and CPython handle surrogate
characters/codepoints-which-aren't-characters.  They are wrapped with
`self.assertRaises(AssertionError)` so we will notice once they start
passing.

https://github.com/RustPython/RustPython/issues/935 is most likely
related.
