tests/acceptance/boot_linux_console: Do not use VGA on Clipper machine
As we only read the serial console, we don't need to force a
VGA display. This fixes when running a binary built with
--without-default-devices:
ERROR: qemu-system-alpha: standard VGA not available
We also need the '-nodefaults' argument to avoid:
ERROR: qemu-system-alpha: Unsupported NIC model: e1000
