configure: Replace git:// and http:// with https://

Obtaining code over an insecure transport is a terrible idea for
blatently obvious reasons.  Even for non-executable data, insecure
transports are considered deprecated.

This patch enforces the use of secure transports in the build system.
Some URLs returned 301 or 302 redirects, so I replaced them with the
URLs that were redirected to.
