fuel, armband: build, deploy: export TERM="vt220"

Since we do not actually parse our build/deploy logs for color chars,
set the terminal to "vt220".

This will silence quite a few of colorization special identifiers,
but NOT all of them (e.g. `tput sgr0` still prints a sequence).

For Fuel@OPNFV build process, we also need to workaround docker
terminal settings not being passed down when using a tty (see [1]),
which will be fixed in Docker 1.13+. This fix is handled in [2].
