Vincent Li cf5df05796 flash-images: add serial console linux command 
Add the missing serial linux command so the
flash image can be converted to qcow2, the
bpfire qcow2 image can be deployed in KVM
virtual environment through serial console
installation.

for exmaple:

virsh define BPFire-VM.xml
virsh start BPFire-VM
virsh console BPFire-VM

we will have serial console access to BPFire
VM and the installation will start.
