authplugin-example.py: Flush stderr.

Browse Source 
Python 3's stderr was fully-buffered when non-interactive, unlike
Python 2 and more or less everything else, until 3.9 in 2020(!):
https://bugs.python.org/issue13601

(It would be less faff to sys.stderr.reconfigure(line_buffering=True)
at the start, but that was only added in 3.7, whereas the 'flush'
argument to print() dates back to 3.3, so I chose that to minimise
the risk of version dependencies getting in the way of using this as
a working example.)
