[PATCH] alsactl: Only start restore service when asoundrc file exists

[Ikey Doherty <ikey@solus-project.com>]

This solves the chicken and egg problem on fresh installations whereby
the alsa state file does not yet exist, and alsa-restore unit attempted
to launch without first having a state file.
