networkd: be more defensive when writing to ipv4/ipv6 forwarding settings

1) never bother with setting the flag for loopback devices

2) if we fail to write the flag due to EROFS (which is likely to happen
   in containers where /proc/sys is read-only) or any other error, check
   if the flag already has the right value. If so, don't complain.

Closes #469
