Depencency chain:
gnome-software -> gnome-softare-plugin-apk -> gnome-software-lib -> gnome-software
is broken.
Application should not depend on its own plugin,
instead plugin should probably be installed using
install_if="gnome-software apk-tools".
This is needed to unblock BPO:
master/x86_64/gnome-software-9999_git20211203-r0.apk (missing depends: gnome-software)
[ci:skip-build] already built successfully in CI
