tests: Force Python I/O encoding for check-qapi-schema

test-qapi.py doesn't force a specific encoding for stderr or
stdout, but the reference files used by check-qapi-schema are in
UTF-8.  This breaks check-qapi-schema under certain circumstances
(e.g. if using the C locale and Python < 3.7).

We need to make sure test-qapi.py always generate UTF-8 output
somehow.  On Python 3.7+ we can do it using
`sys.stdout.reconfigure(...)`, but we need a solution that works
with older Python versions.

Instead of trying a hack like reopening sys.stdout and
sys.stderr, we can just tell Python to use UTF-8 for I/O encoding
when running test-qapi.py.  Do it by setting PYTHONIOENCODING.
