Deprecate and expire in 1 month.

The port has been unfetchable for a while now, marked BROKEN since November
2015 and unmaintained.

While here, switch MASTER_SITES to the https version to try to silence
portscout: accessing broken links with the http version results in an HTTP 302
response that I think causes portscout to report that new versions are
available even though they are not. Since broken links in the https version
result in HTTP 404, hopefully this will make portscout quiet again.
