Fix Windows issue related to PR #5207

( see comment https://github.com/Theano/Theano/pull/5207#issuecomment-260430352 ). In Windows there are some issues with os.listdir(path) when path is surrounded with quotes. So it's better to remove quotes (if present) at the start and the end of paths passed to this function. Checking of ldflags parts is also modified to better handle quotes around "-L" args.
