flake8 fixes after upgrading it to 3.6.0

- bare excepts weren't an error before? huh. too lazy to fix them right now though, given the rest of this code...
- ambiguous variables are new; not clear why they're ambiguous besides being short. but, fixed
- some wacky non-escape sequence in some awful gssapi output strings. whatever. removed
