test-install: Wait for network in the lxc container. 

Ubuntu 20.04 "focal" comes up to runlevel 5 several seconds before it
is able to successfully resolve hosts, causing `prepare-base` to fail
while fetching from the apt repositories.

Add an additional check to verify that outbound networking is running
before returning from `lxc-wait`.
