Moving javadocs path in jenkins

[Andrew Musselman <an...@gmail.com>]

Stevo, we saw a failed build in Jenkins due to:

Publishing Javadoc

Which makes sense since mrlegacy exists no more; I moved that path to
distribution, will see what happens.

Please change it if you think there's a better place.

Thanks!
