package/libzlib: Switch to using HTTPS
Switch to using HTTPS for downloading libzlib from zlib.net.
(zlib.net doesn't default to HTTPS but does suggest HTTPS in the permalink
for the latest zlib release. Also works better with some corporate firewalls
that get suspicious about zlib for some reason.)
