Add gn dependency between sync_performance_tests and used resources

Test sync_performance_tests uses the following resource files:
- $root_out_dir/chrome_100_percent.pak
- $root_out_dir/chrome_200_percent.pak
- $root_out_dir/locales/en-US.pak
- $root_out_dir/resources.pak
But there were no any dependency in build.gn between tests and the resources.
The resources were not regenerated during sync_performance_tests build.

The change contains the fix of the resources generation used by sync_performance_tests.
