coredns package template overwrites config file

[tommyalatalo]

The coredns package template overwrites the user's /etc/coredns/Corefile config on update, possibly breaking the service on reboot etc. Can this be updated so that the file is not overwritten if it exists?

The issue is probably this line: https://github.com/void-linux/void-packages/blob/master/srcpkgs/coredns/template#L30
