[salt-formulas] Add & enable armband formula

AArch64 specific formula, mostly tweaking nova conf / installing
virtualization layer prerequisites:
- install qemu-efi;
- install vgabios;
- fix missing link for vgabios binary blob;
- nova conf: cpu_model=cortex-a57 (only for virtual deploys);
- nova conf: virt_type=qemu (only for virtual deploys);
- nova compute conf: virt_type=qemu (only for virtual deploys);
- nova conf: pointer_model=ps2mouse since AArch64 has no USB tablet;
