bpo-28180: Standard stream & FS encoding differ on Mac OS X (GH-2208)

In the C locale on Mac OS X, the default filesystem encoding
used for operating system interfaces is UTF-8, but the
default encoding used on the standard streams is still ASCII.

Setting the POSIX locale also behaves differently from setting
other locales on Mac OS X, so skip that in the test suite for now.
