tests: Fix ubuntu.i386 image initialization

The apt-get commands we run through ssh expect certain features of the
tty, and refuses to work if /dev/null is used. It is ugly, but easy to
satisfy.

Actually, there is no reason to hide the output. It just makes things
harder to diagnose. We can always redirect in the Makefile, so don't do
it conditionally here.
