Backport fix of Debian #832637 to xenial, cups-browsed delays shutdown by connecting to localhost:631 while listening only to domain socket

[Iiro Laiho]

Please backport the fix of this Debian bug to Xenial.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=832637

To quote from there:

"The problem is most probably caused by inconsistency in how cups-browsed
accesses the local CUPS daemon, for some accesses it uses the domain
socket (which made it mostly well working in your case) and at other
places, especially also during shutdown, it accesses localhost:631 (this
is why it hangs on shutdown), independent of configuration."

It is fixed in Debian's cups-filters/1.11.4-1.

This is NOT a duplicate to #1579905 as is noted in it's comments.
