tinc service: host names from /etc/hosts don't work when chroot is used

[nh2]

The nixos tinc service defines chroot = true as a default, but according to mailing list reply from the tinc author, host names from /etc/hosts (which especially nixops relies on) don't work by default in chroot because tinc can't see /etc/hosts.

The solution is to place a copy of /etc/hosts in the chroot dir when chroot = true is used.

CC @wkennington @ericsagnes @fadenb @joachifm @tg-x as they committed to that service in the past and might be intrested.

still very important for me

Apparently normal DNS doesn't work either in chroots, e.g. it cannot resolve myhost.example.com.
