[OE-core] [PATCH 1/2] alsa-state: install init script only when 'sysvinit' is in DISTRO_FEATURES

[Chen Qi]

The /etc/init.d/alsa-state is totally useless for a systemd image.
Its functionality has been replaced by alsa-state.service files.

So if 'sysvinit' is not in DISTRO_FEATURES, installing this script doesn't
make any sense.
