examples/udhcp/simple.script: fix resolv.conf update if it is a dangling symlink
If /etc/resolv.conf is a symlink to a tmpfs and the actual file does not already exist, "readlink -f" will not detect it as symlink. Explicitely check for that condition before and touch the file, making the other code work as intended.
