getty-generator: Enable getty on all active serial consoles.
This enables a getty on active kernel consoles even when they are not the last one specified on the kernel command line and mapped to /dev/console. Now the order "console=ttyS0 console=tty0" works in addition to "console=tty0 console=ttyS0".
