<i18n dev> [8] Request for Review: 6863624 : java/util/Currency/PropertiesTest.sh writable check is incorrect

[Naoto Sato]

Hello,

Please review this test case fix:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6863624
http://cr.openjdk.java.net/~naoto/6863624/webrev.00/

Basically it enforces the check for non-writable JDKs, with a workaround 
for Cygwin's inconsistent behavior for `test` command. Changes for 
LocaleProviders are irrelevant for this fix, just the left over from 
previous fix for 8015960.
