nspawn: Don't follow /etc/resolv.conf symlinks

Browse Source 
When we're checking if /etc/resolv.conf exists so we can bind mount
on top of it, we care about whether the symlink itself exists if
/etc/resolv.conf exists and not the file it points to, so add
CHASE_NOFOLLOW to make sure we check existence of the symlink and
not the file it points to.
