util, posix: eliminate encodinglower and encodingupper

2ebe3d0ce91d claims this was needed "to avoid cyclic dependency", but there is
no cyclic dependency.

windows.py already imports encoding, posix.py can import it too, so we can
simply use encoding.upper in windows.py and in posix.py.

(this is a partial backout of 2ebe3d0ce91d)
