Adam Williamson 2d16a3af00 Protect against decoding errors with subprocess text mode
All these are calling subprocess in 'text mode', where it will
try to decode stdout/stderr using the default encoding (utf-8
for us). If it doesn't decode, subprocess will raise an exception
and kobo doesn't handle it, it just passes it along to us, so
things blow up - see https://pagure.io/releng/issue/12474 . To
avoid this, let's set `errors="replace"`, which tells the decoder
to replace invalid data with ? characters. This way we should get
as much of the output as can be read, and no crashes.

We also replace `universal_newlines=True` with `text=True` as
the latter is shorter, clearer, and what Python 3 subprocess
wants us to use, it considers `universal_newlines` to just be
a backwards-compatibility thing - "The universal_newlines argument
is equivalent to text and is provided for backwards compatibility"
