Fix currency-related build failure starting 12/31/2014

[Chris Metcalf]

Our JDK 1.6 and 1.7 builds began failing today with the message "Error: time is more than 10 years from present: 1104530400000".  At midnight Turkish time on Dec 31, 2004, the new Turkish lira (TRY) replaced the old lira (TRL) at 1,000,000:1.  You may note that this was exactly 10 years ago today.

Some enterprising long-ago coder included a sanity test that all currency conversions happen within 10 years of the current moment, but clearly they must have meant "no more than 10 years into the future".  To correct this, I remove the Math.abs() from the code in question.

I admit to not being familiar with the bug submission and patch submission process for OpenJDK, but hopefully as a trivial fix there is no issue with copyright assignment or other technicalities.  I just submit this in hope that it avoids more folks wasting their time on this issue.
