[9] RFR 8030696: Norwegian locales nb_NO and nn_NO should be available locales

[Naoto Sato]

Hello,

Please review the following fix:
https://bugs.openjdk.java.net/browse/JDK-8030696
http://cr.openjdk.java.net/~naoto/8030696/webrev.00/

It basically adds "nb_NO" and "nn_NO" in the returned array from 
Locale.getAvailableLocales(). Also corrected the localized name for "NO" 
in nynorsk.
