This update for cups fixes the following issues:

- Avahi sends an ALL_FOR_NOW event when it finishes sending its cache contents.
This patch makes cupsEnumDests finish when the signal is received so it doesn't
block the caller until the timeout finishes. (bsc#955432, fate#322052)
- The scheduler didn't log messages for jobs at LogLevel "info". (bsc#1021133, bsc#990045)
