Improve how run-time deps (aka "depends") are handled in packages. 

Run-time dependencies declared via "${depends}" are now also part of the
build process, but those are not installed to the master directory; rather
those dependencies are only checked if a binary package exists in a
local repository to satisfy the required version.

Thanks to @dominikh for idea and suggestions.

Dependencies declared via `${depends}` are not installed to the master directory, rather are
only checked if they exist as binary packages, and are built automatically by `xbps-src` if
the specified version is not in the local repository.
