iotests: Use Python byte strings where appropriate
Since byte strings are no longer the default in Python 3, we have to
explicitly use them where we need to, which is mostly when working with
structures. It also means that we need to open a file in binary mode
when we want to use structures.
On the other hand, we have to accomodate for the fact that some
functions (still) work with byte strings but we want to use unicode
strings (in Python 3 at least, and it does not matter in Python 2).
This includes base64 encoding, but it is most notable when working with
the subprocess module: Either we set universal_newlines to True so that
the default streams are opened in text mode (hence this parameter is
aliased as "text" as of 3.7), or, if that is not possible, we have to
decode the output to a normal string.
