The package deployment/running is in flux at the moment. In order to get all the other tests on to the main Fuchsia waterfall, disable the ~25 tests that require external files (for launching child processes, loading modules, or data files) because those operations all fail on Fuchsia-without-packages right now. Upstream this is PKG-46. Once test packaging and running has been resolved, this can be reverted. These tests are still run when building Crashpad standalone on Fuchsia as the standalone build simply copies all the relevant data files to the device in /tmp.
