Add default packages even if they are not reachable by main package

This fixes the problem of not exposing --with-cudac to cupynumeric by default.

Would it makes sense to have the option to turn this off, either cm = ConfigurationManager(argv, MyPackage, include_default_deps=False) or cm.setup(include_default_deps=False)?

Hmmm possibly. But it would add a bit of complexity (not literally -- its just a bool -- but by giving the caller a choice). To give some background here: aedifix was originally the build system for just Legate (and actually lived in the Legate repo under config, much like its inspiration, BuildSystem).

When we decided to extend it to cupynumeric, we moved it to this repo and made it project agnostic (though it already mostly was, as I figured this move would eventually happen). But it was only as agnostic as Legate or cupynumeric needed it to be.

All this is to say: let's add this when we need it. aedifix is purely an in-house tool. It exists to serve exactly Legate and cupynumeric, and not a single project more (though maybe legate-sparse). Any features that it has, are because either Legate or cupynumeric needed them.

But I am open to having my mind changed, just don't want to complicate things apriori. WDYT @tisaac @bryevdv?

I agree.
