ICMP errors don't seem to be correctly propagated in all cases

Description

Typically, errors like ICMP host unreachable appear to get propagated back as failures to the respective socket client, i.e. when attempting a TCP connection. However, in the case of a direct ICMP user like the ping command, this doesn't appear to occur properly, as it has code to detect/handle ICMP error replies and print them, but this doesn't seem to actually get triggered when running a ping to such an unreachable host on Haiku, while it does when pinging from FreeBSD to the same target host and the same ping code.
