Josh Bleecher Snyder 4b1f2ae382 tstest/integration: generate deps for all platforms in deps generator
We have different deps depending on the platform.
If we pick a privileged platform, we'll miss some deps.
If we use the union of all platforms, the integration test
won't compile on some platforms, because it'll import
packages that don't compile on that platform.

Give in to the madness and give each platform its own deps file.
