Run npm nodejs job with Phantomjs browser

This patch update browser from Chrome to Phantomjs
in karma.conf.js because nodejs job fails with Chrome
browser as not able to access some URL.
So let's switch to Phantomjs browser now then we can
use Chrome browser in future once this issue is resolved.

It also adds libfontconfig1 in bindep.txt as phantomjs
requires libfontconfg[1].
