Change the sysvinit-inittab bbappend in meta-virtualization use
start_getty instead of just getty, start_getty does a 'test -c' before
starting getty on the device. This is how sysvinit-inittab handles
SERIAL_CONSOLES. Alternatively the meta-virtualization bbappend could
just expand SERIAL_CONSOLES.
