avahi: fix error at boot time for avahi-daemon.service
The following error messages appear now and then at boot time.
avahi-daemon/chroot.c: open() failed: No such file or directory
Failed to open /etc/resolv.conf: Invalid argument
The problem is about /etc/resolv.conf. In Yocto's systemd based
systems, it's a symlink to /etc/resolv-conf.systemd which in turn
is a symlink to /run/systemd/resolve/resolv.conf. The systemd-resolved
service handles creation of /run/systemd/resolve/resolv.conf file.
So if avahi-daemon is started before systemd-resolved, the error messages
appear.
Fix this problem by making avahi-daemon start after systemd-resolved.
