basic.sh: Add support for HEADLESS mode via environment

Browse source 
Currently if a user wants to run in headless mode they have to edit the
basic.sh script by hand.  Rather than making them edit the script by hand,
add support for a HEADLESS environment variable which can be set to 1 to
add necessary command line arguments to qemu.
