Update defaults for `aflags_updatable` rust_binary.

The `aflags_updatable` target now uses `aflags_updatable.defaults`
instead of `aflags.defaults`. I think this was just a typo when things
were copied over to config infrastructure. Needed for this change because I'm deleting the now-unused defaults from platform aflags.

Test: manual using the aconfig demo app
