Qt WebEngine and (deprecated) Qt WebKit are not compatible with each other,
they provide different sets of classes. And it looks like upstream stellarium
only supports Qt WebEngine, not WebKit.

Good news is that Qt WebEngine support is optional and you can just build
without it on architectures where it's not available. This can be achieved by
limiting the build-dependency:

  qtwebengine5-dev (>= 5.15) [amd64 arm64 armhf i386 mips64el],

I did that in Ubuntu [1] and the package built on all Ubuntu's architectures.
