Eli Schwartz 9c817b6549 libmakepkg: implement extendable source protocols
Lookup the existence of matching functions for each protocol, and
fallback on the generic file handler. New source protocols can then be
added via thirdparty libmakepkg drop-ins without requiring modifications
to source.sh

Fixes FS#49076
