Subject: [PATCH] nixos: fix avahi connectivity for shairport-sync module

The shairport-sync service currently fails to start with the error

shairport avahi_entry_group_new failed

This problem seems to have been introduced by

cdd7310a503481e3c40266be45b6b8256d95ecbd

After some trial and error I concluded that the attached commit is a minimal
fix.
