Subcommand to return names of parent packets of dependencies

It'd be great to have something like that because recursive-deps right now only returns the verbatim $makedepends instead of the packages that build the particular $makedepends

E.g. foo makedepends on bar-dev

The command should return bar, instead of bar-dev.

That way one can use the output of the subcommand for a simple for loop to build all the dependencies and the packet itself.
