MAINT: Fix some pyflakes warnings in numpy/core/*.py

These fixes are not agressive as some of the code is complicated
and it is better to be careful.

The files numeric.py and numerictypes.py are not easily analysed
and the latter is self modifying. Pyflakes generates a number of
invalid warnings for those files.
