Subject: [PATCH] background: Update animations when coming back from suspend

We currently reload animated backgrounds on timezone changes, but
there are other cases where the time can change unexpectedly and
the background no longer matches the time of day. One case we can
easily handle is when coming back from suspend, so do that.
