multi-boot for openstack/qcow images

Make stock FreeBSD more useful for people wishing to use them. The
QEMU folks suggested this change. It adds a serial console which
allows them to interact with FreeBSD from the earliest moments. This
allows them to configure FreeBSD via the serial port to set it up for
CI use.
