x86_64: set reset vector when using bios

BIOS expect all the cpus to be pointed at the i386 reset vector before
boot. We can't guarantee that a fresh vcpu will be pointed to the reset
vector by default, so we should set the reset vector when we're
configuring the vcpu when we're using a BIOS.

Cherrypick from downstream branch.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
