sbox will generate a random directory for the output root, and most tools will encode that directory name in the output target of the depfile. So embed the library from dep_fixer into sbox so that it can rewrite the output filename to a static (reproducible) value. Ninja doesn't care what that value is, so it's just "outputfile". Also fix up rule_builder to actually tell sbox about the depfile.
