Well, you can't have this both ways :)

Bitbake doesn't know which modules this package will produce since its
using PACKAGES_DYNAMIC. It does its best effort to try and find DEPENDS
but it can't take the regexps and come up with
"pulseaudio-module-console-kit", hence it doesn't see the RDEPENDS.
There isn't any generic way we can teach it to do that either. If it
did, it would simply always build consolekit which you say you don't
want so its not relevant anyway.

So basically, you need to decide whether you want consolekit enabled or
not and build accordingly, there is nothing you can do within bitbake to
"mind read" what the image is going to want...
