unit tests: Use universal_newlines everywhere
unit tests: Use universal_newlines everywhere

This approach is locale-independent and more correct. For instance, this
will work with UTF-16 while the previous approach with binary comparison
would not.

This also removes the need for doing an explicit decode to utf-8 which
is lossy and can fail by yielding no output at all.
