RFR: JDK-8042348: Copyright link in Javadoc page for Java SE 8

[Tim Bell]

Hello Erik:

> Please review this small patch to javadoc generation. The Copyright 
> footer, at the bottom of the page, should be a link, but in jdk8 and 9 
> it isn't. This is caused by COPYRIGHT_URL being empty if 
> JDK_MINOR_VERSION is not 7. I see no reason to have a jdk version 
> dependency on this URL since the value isn't dependent on jdk version.
>
> This will likely need a backport to 8 too.

Looks good to me.
