It might be better if the STATEDIR creation would be done in outside of
connman like by tmpfiles.d or similar. Then we could fallback to older
behaviour (== writing resolv.conf to /etc) if STATEDIR does not exist.
With the current code, the libc resolving might not work if user has not
managed to correctly setup /etc/resolv.conf to be link
into /var/run/connman/resolv.conf

Here could fallback to older behavior and write to /etc if the new
directory does not exist.
