alsa-state: ignore 'No soundcards found' error in pkg_postinst

If there is no soundcards on the target (e.g. qemu), the pkp_postinst
function will report an error:
  alsactl: load_state:1735: No soundcards found...
  pkg_run_script: package "alsa-state" postinst script returned status 19.
  opkg_configure: alsa-state.postinst returned 19.

Pass '-g' option to alsactl to ignore this error.
