[PATCH] python: Check "buffer" when writing to sys.stdout for python2 compat.

[Tobias Mueller]

* lang/python/tests/support.py (print_data): added buffer check
--

When running with something like make -C lang/python check verbose=2 the
test would fail under python2, because the file objects do not have a
buffer property.
