Remove our urlparse wrapper

It has not been necessary since we dropped support for Python 2.6.
See https://github.com/python/cpython/commit/8c6d9d7 and
https://bugs.python.org/issue2987.

Be sure to keep a `urlparse` name in utils, though; swauth (at least)
still expects there to be a swift.common.utils.urlparse.
