JDK 9 RFR of two fixes to make/Javadoc.gmk

[Joe Darcy]

Hello,

Two JDK 9 fixes to  make/Javadoc.gmk for review:

     JDK-8048302: Update bug reporting URL in make/Javadoc.gmk
     JDK-8048321: Enabled doclint warnings in docs build
     http://cr.openjdk.java.net/~darcy/8048302.0/

The two portions of the patch below should be clear.

The old sun.com URL for reporting bugs was retired and replaced with a 
java.com URL.

After some recent fixes in langtools, the langtools API sources are 
doclint clean, meaning the doclet, taglet, and tree API doc command 
should enforce that property using the doclint option.

The core API build is doclint clean on a few properties and those are 
also enabled by this change.

I verified a docs build succeeds with this changes.

Thanks,

-Joe
