Subject: [PATCH] Only include specifically-requested packages in radioconda
 metapackage.

Including the fully solved list of packages is fragile to packages
getting marked broken or having their metadata rewritten, making the
radioconda metapackage uninstallable. This doesn't completely solve that
(nothing really can), but it does make the metapackage still fulfill its
intended purpose while hopefully remaining installable more often.
