[Merge] ~slyon/ubuntu-seeds/+git/platform:lunar-mir-pkgconf into ~ubuntu-core-dev/ubuntu-seeds/+git/platform:lunar

[Lukas Märdian]

I'm not sure if we need to change any other component in the distro to make the pkg-config -> pkgconf change, besides this seed. That's why I'm asking for Steve's review on this change.
