[PATCH] docs: make maintainers_include work with Python 2

[Jonathan Corbet]

The MAINTAINERS file contains UTF-8 data, so Python 2 code has to be
explicit about moving it into the Unicode realm.  Explicitly decode all
data from the file as soon as we read it.

This hack can go away once we deprecate Python 2 support.
