Wrap calls to start_getty with ttyrun, so that getty isn't started if the device doesn't exist. As we know start_getty is only called when the device exists we can remove the partial workaround for this problem in that scripts too. This neatly obsoletes SERIAL_CONSOLES_CHECK, whose sole purpose was to check what terminals are present at boot and rewrite inittab. Notably, this meant that SERIAL_CONSOLES_CHECK made using a read-only rootfs impossible.
