[IronPython] Standard encodings

IronPython doesn't load standard encodings.

CPython implicitly tries to import encodings/__init__.py on first
codecs lookup, and this registers codecs search function which imports
encodings/<encoding_name>.py on demand. Any ImportError is ignored.

A simple workaround is to have "import encodings" in site.py. After
the import IronPython behaves the same.
