Remove path hacks that break chardet in Python 3. Closes #858.

This replaces the sys.path hack with a slightly less objectionable
sys.modules hack.

Both have the effect of making the vendored lib's absolue imports work
as expected when oauthlib isn't installed. The sys.modules hack doesn't
insert the rest of the vendored crap in a global path, however.
