Title: Fix Debian 7 build failure: Make apt-get non-interactive to workaround interactive openssl update prompt

A recent openssl update in Debian 7 brings up an interactive prompt which hangs indefinitely, causing `veewee vbox build` to timeout (presumably `libssl-dev` https://github.com/jedi4ever/veewee/blob/master/templates/Debian-7.4.0-amd64-netboot/base.sh#L4)

I've checked Debian-7.0-i386-netboot and Debian-7.4.0-amd64-netboot, the problem occurs in both.

This PR sets an environment variable which should force the default action to be taken without prompting.
