classes: rootfs-postcommands: autologin root on serial-getty

when empty-root-password AND serial-autologin-root are part of the
IMAGE_FEATURES, save some of the developers time by not having to type
the (then still sole) 'root' username on the serial console after each
and every reboot

this is done by inserting '--autologin root' into the command line of
the responsible 'getty' service
