skawarePackages: factor out the common parts

Introduce a `skawarePackages.buildPackage` function that contains the
common setup, removing a lot of duplication.
In particular, we require that the build directory has to be empty
after the `fixupPhase`, to make sure every relevant file is moved to
the outputs.

A next step would be to deduplicate the `configureFlags` attributes
and only require a `skawareInputs` field.
