libmakepkg: fix missing or inaccurate interdependencies

When the executable checking was refactored into libmakepkg, it carried
with it, usage of $E_* error codes, which need to be declared from
error.sh but are only available when the parent program already sources
error.sh; additionally, message.sh was only loaded in a parent
library, but not where it was needed, and option.sh was often loaded
when it wasn't needed at all.

util.sh, meanwhile, has always depended on message.sh functions.
