RFR: JDK-8204973: Add build support for filtering translations

[Erik Joelsson]

Hello,

Here is a new version of the patch:

http://cr.openjdk.java.net/~erikj/8204973/webrev.02/

Changes from last time:

* Made the regexp for finding locales more correct. It still does not 
try to match 3 letter language strings because doing so triggers a large 
amount of false positives in our souce tree.

* Added another accepted locale (en_US_POSIX) that is now matched by the 
improved regexp.

* Added more locales to the exclude list as they were now discovered by 
the improved regexp.
