Emit the bundles under gen/internal/electron/js2c so js2c gives them internal/electron/js2c/* ids: they leave module.builtinModules, cannot be required or fetched with process.getBuiltinModule() from app code (which crashed under ELECTRON_RUN_AS_NODE), and parallel/test-process-get-builtin is re-enabled.
