[8u] 8222108: Reduce minRefreshTime for updating remote printer list on Windows

[Zhengyu Gu]

I would like to backport this patch to 8u, as it is in Oracle's 8u.

The patch does not apply cleanly. In early backports, there were 
conflicts and we kept 8u code in old styles.

E.g. RemotePrinterChangeListener still inherits from Thread, instead of 
implementing Runnable in new code.
