[12] RFR:8210490:TimeZone.getDisplayName given Locale.US doesn't always honor the Locale

[Rachna Goel]

Hi,

Kindly review fix to JDK-8210490.

Bug: https://bugs.openjdk.java.net/browse/JDK-8210490

Webrev: http://cr.openjdk.java.net/~rgoel/JDK-8210490/webrev.05/

This is a regression caused by JDK-8202537, where for timezones such as 
Etc/GMT-5, display names got formatted according to default locale.

Fix is to specify locale, which was specified in 
timezone.getDisplayName() method.

Thanks,
Rachna
