fix(mkimage): log console boot messages to hvc0

VZ has support for serial console logging but the device is different from Qemu. VZ uses the hypervisor virtual console device instead. This change modifies the bootloader to add hvc0 as a device to log console messages to on boot.

Note this has no effect on the tty serial logging.
