Bump Lucene version to 4.6.0
Bump Lucene version to 4.6.0

Also remove unused artifacts from the Buck file.

Gerrit gitblit plugin must ship Lucene binaries in shaded jar, because
the versions of Lucene that Gerrit and Gitblit ship are different.

This change and this pull request [1] harmonize the Lucene versions in Gerrit
and Gitblit distributions.
