zsync-curl: add recipe

zsync is a tool that is similar to rsync but optimised for transfering
single large files where you have a previous version of the file locally.
These qualities make it an excellent choice for transfering built images
between hosts.

zsync-curl is a maintained fork of the original zsync, that uses curl for
HTTP requests allowing it to connect to HTTPS servers.
