package/alsa-utils: fix systemd install

Buildroot commit e859686460a30af0868d68810645c2208562039f bumped alsa-
utils to 1.2.15.1 including upstream commit
https://github.com/alsa-project/alsa-utils/commit/f047a8a66917960ef5a9ff0e41de507f0e58f381
which moved the systemd files to alsactl/conf subdirectory.

Adjust ALSA_UTILS_INSTALL_INIT_SYSTEMD accordingly to fix build error.
