hgweb: validate WSGI environment dict

The wsgiref.validate module contains useful functions for validating
that various WSGI data structures are proper.

This commit adds validation of the environment dict to our built-in
HTTP server, which turns an HTTP request into an environment dict.

The check discovered that we weren't always setting QUERY_STRING,
which would cause the cgi module to fall back to sys.argv. So we
change things to always set QUERY_STRING.

The check passes on Python 2 and 3.
