alsa-state: fix pkg_postinst and set INHIBIT_UPDATERCD_BBCLASS

As alsa-state inherits update-rc.d, the update-rc.d part inpostinst script
has already been handled in update-rc.d.bbclass.

Besides, we need to set INHIBIT_UPDATERCD_BBCLASS to "1" if 'sysvinit'
is not in DISTRO_FEATURES. This is because the init script is not installed
in such situation, adding update-rc.d part in the preinst/postinst scripts
just makes no sense.
