[Qbs] building android aab package help

[Raphael Cotty]

The android tool aapt2 manages resources. Some output files required for
the aab package need to be in the protobuf format. Also the R.java
generated by aap2 is different from apk to aab.
That's what I meant by context.
The aab package doesn't need the apk package to be built.

Because both packages need exactly the same input and because some of the
rules are the same (java ones, dex one) I think it makes sense to build
both packages by the same product.
