udhcpc: use readlink rather than realpath
The realpath utility requires all paths exist when canonicalizing symlinks. If /etc/resolv.conf points to a tmpfs, then it might not exist initially. Use `readlink -f` so that we follow all symlinks that are available. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
