initscripts: populate-volatile: suppress read-only-rootfs warnings

rm: can't remove '/etc/resolv.conf': Read-only file system
ln: /etc/resolv.conf: File exists

/etc/default/volatiles contains an entry:
l root root 0644 /etc/resolv.conf /var/run/resolv.conf

which causes populate-volatile.sh to execute the following in link_file():
  if [ -L \"$2\" ]; then
    [ \"\$(readlink -f \"$2\")\" != \"\$(readlink -f \"$1\")\" ] && { rm -f \"$2\"; ln -sf \"$1\" \"$2\"; };
  elif [ -d \"$2\" ]; then
    ...

At the time the image is created, /etc/resolv.conf is already a
symlink to /var/run/resolv.conf, but at boot time when
populate-volatiles.sh is run, /var/run/resolv.conf doesn't
exist, causing it to try to rm -f and ln -sf which of course
fails due to the read-only filesystem.
