Subject: Have Soong try to enforce that genrules declare all their outputs.

This causes Soong to put the outputs of each genrule into a temporary
location and copy the declared outputs back to the output directory.
This gets the process closer to having an actual sandbox.

Bug: 35562758
Test: make
