Fix an open redirection vulnerability in the http.server module when
an URI path starts with // that could produce a 301 Location header
with a misleading target. Vulnerability discovered, and logic fix
proposed, by Hamza Avvan (@hamzaavvan).

Test and comments authored by Gregory P. Smith [Google].
(cherry picked from commit 4abab6b)

Up to the RM team to decide is this minor security fix is worth going into such an old branch. Consider our statement about http.server in https://docs.python.org/3.7/library/http.server.html.
