qapi: Force UTF8 encoding when parsing qapi files 

Commit d4e5ec877 already fixed things to work around Python 3's
lame bug of having LC_ALL=C not be 8-bit clean, when parsing the
main QMP qapi files; but failed to do likewise in the tests
directory.  As a result, running 'LC_ALL=C make check' fails on
escape-too-big and unicode-str when using python 3 with a nasty
stack trace instead of the intended graceful error message that
QAPI doesn't yet support 8-bit data (the two tests contain
Unicode é, when parsed in UTF-8; they represent something
different when parsed in a proper single-byte C locale, but that
doesn't matter to the error message printed out, provided that
brain-dead Python hasn't first choked on the input instead of
being 8-bit clean).

Ideally, we'd teach the qapi generator scripts to automatically
slurp things in using UTF-8 regardless of locale, and to honor
content that is not limited to 7 bit data rather than gracefully
erroring out; but until then, since our graceful error depends
on python parsing 8-bit data (even if nothing we generate uses
8-bit data), our quick fix is to use the right locale when
running these tests.
