pkgman: Add command resolve-build-dependencies
This is a service command for haikuporter. It resolves the dependencies for a package to be built and lists them, so that haikuporter can prepare the build environment accordingly. The implementation isn't quite finished yet. Currently the packages are printed only with name and version, while it would probably be more helpful to print the path of the package file. Also, the package itself (respectively a dummy package) is printed as well.
