UnlockDialog: honor org.gnome.desktop.screensaver.user-switch-enabled

The screensaver schema has a key that it is meant for locking down
the ability to switch user when the screen is locked, but support
for it was not implemented in the new screenshield.
Fix that by checking the key before creating the button.
