board/qemu/start-qemu.sh.in: support launching with host system's qemu

Provides the ability to use a host system's QEMU. While a Buildroot
generated QEMU should work for most cases, a developer may wish to use
the system's QEMU for options which may not have been configured in the
Buildroot's QEMU build (e.g. configuring a different display mode).
