pkg_use_enabled: return early for built pkgs
Built/installed packages have frozen USE settings, so there's no sense
in considering them for autounmask USE config changes. They'll simply
be rejected by select_package, and an unbuilt ebuild will be selected
instead. This will fix bug 371423 by avoiding unnecessary use_reduce
calls on the deps of installed packages.
