Boot using BIOS from /etc/firmware/vmm-bios by default.

Instead of using the internal "vmboot", VMs will now be booted using
the external BIOS firmware in /etc/firmware/vmm-bios (which is subject
to a LGPLv3 license).  Direct booting of OpenBSD kernels or
non-default BIOS images is still supported for now using the -b/boot
option that is replacing the -k/kernel option.

As requested by Theo, vmd(8) fails if neither the default BIOS is
found nor a kernel has been specified in the VM configuration.  The
"vmm" BIOS has to be installed using fw_update(1), which will be done
automatically in most cases where the OpenBSD can fetch it after
install/upgrade.
