bpo-36020: Remove snprintf macro in pyerrors.h (GH-20889)


On Windows, GH-include "pyerrors.h" no longer defines "snprintf" and
"vsnprintf" macros.

PyOS_snprintf() and PyOS_vsnprintf() should be used to get portable
behavior.

Replace snprintf() calls with PyOS_snprintf() and replace vsnprintf()
calls with PyOS_vsnprintf().
(cherry picked from commit e822e37946f27c09953bb5733acf3b07c2db690f)
