xbps-src: depuplicate output of setup_pkg_depends
Issue #21044 raised problem of setup_pkg_depends returning duplicate results after depends of subpackages were included. Specifically, problem was performance and triggering failures of xbps-fbulk.

I was unable to reproduce fbulk's misbehavior, as show_pkg_build_depends deduplicates its output. Yet I don't see reason for listing duplicates here.

Please merge if you find it good.
