Subject: makepkg: refactor archive compression for reusability

This allows for more easily extending the list of allowed compression
methods, as it has to be modified in only one place.

Also allow the user to specify their own preferred command + options for
source packages in addition to compiled packages. Currently,
makepkg.conf(5) erroneously claims this is already possible.
