RFR 6726154: javadoc generated with incorrect version in comment

[Alexander Zuev]

Hello,

   please review my fix for the issue JDK-6726154: javadoc generated 
with incorrect version in comment

   The problem is that in the build time we are using bootstrap JDK to 
run javadoc classes so it reads incorrect
JDK version. In order to retain correct version i've changed 
makefiles/BuildLangtools.gmk to create resource bundle
with the correct version information - the same way version is retained 
for javac or javap.

   The fix can be found here:
