rework resolvconf handling

When building host with resolvconf and /run:

| # ls -la /etc/resolv.conf
| lrwxrwxrwx 1 root root 31 Sep 10 13:15 /etc/resolv.conf -> /etc/resolvconf/run/resolv.conf
| # readlink -f /etc/resolvconf/run/resolv.conf
| /run/resolvconf/resolv.conf

... then test -L and test -d will result both in the same
result for testing /etc/resolvconf/run. So instead let's
try to identify the type using readlink.
