Add smackfs check to Installer service.

The app installation was failing under the non-smack environment.
One additional check for the existence of the smack is now added to
prevent the Installer from applying smack rules to the kernel, when
there is no smack security enabled.

The same kind of check is also added to uninstall-app functionality.
