Subject: [PATCH] authPrompt: Wiggle error messages coming from the Fingerprint
 service

When error messages are coming from the fingerprint service they are actual
failures due to an user input in some device, in so in such case we
can highlight this by using a wiggle effect.

This mimics what has been done in gnome-control-center fingerprint panel
and part of [1].
