Modify install script for java/ant based on trying on first upstream bot.

Upstream bots had errors installing from debian packages.  I changed to download
and install the same packages with sudo apt-get.  Tested locally and on the
upstream bot, and it seems to work.  Need to test on "fresh" bot with no java
or ant already installed.
