Wait for the queue to timeout...

cups-polld relies on the BrowseTimeout stuff to remove the queue.

lpstat has no cache and only asks a single server (usually localhost)
for its list of queues.  The server (cupsd) keeps track of the
available printers - the printcap file is updated by the scheduler with
the current list of printers, but is only there for legacy apps that
look at the printcap file instead of using IPP requests, CUPS API,
lpstat command, etc.
