alsa-utils: move ${datadir}/init files to alsactl package.

alsa-utils: move ${datadir}/init files to alsactl package.

The alsa-utils-speakertest contains some files from ${datadir} directory
that are not correct, the files from  ${datadir}/init directory should
be included in alsa-utils-alsactl package instead.

This patch moves the ${datadir}/init files to alsactl package and fixes
following error at boot stage:

  /usr/sbin/alsactl: parse:1655: Unable to open file '/usr/share/alsa/init/00main': No such file or directory
