Add seam-international implementation dependency

Before this fix, startup of the container with seam-faces as dependency
would fail with unsatisfied injection dependency of Locale type for
seam-international-api's ApplicationBundles.appLocale property.

This change adds seam-international implementation as runtime scope
dependency of seam-faces implementation.
