Patches needed to make this work on L4T 4.4.38-tegra

The installation instructions do not hold for current out of the box Jetson TX2, which at this time is 4.4.38-tegra. There are some slight changes that need to be made. The first is enabling the universe repositories in /etc/apt/sources.list so the pre-build script can, at the least, successfully sudo apt-get install python-pip:

The second is to pass the pyzmq version that works nicely with jupyter notebooks to pip:

I believe there is a PR for the latter fix. Running pip install --upgrade may work as well instead of that patch. See jupyter/notebook#3579

Further, avahi-autoipd needs to be updated/reinstalled else python notebooks may fail when attempting to use dhclient with tegra-ubuntu root: /etc/dhcp/dhclient-enter-hooks.d/avahi-autoipd returned non-zero exit status 1 in syslog.

sudo apt-get install avahi-autoipd
