arp should warn when it can't exec netstat
The arp command execs netstat when using arp -a. However, if it can't execute netstat, then it just silently fails and doesn't print anything, just exiting with 1. It makes it very hard for most folks to realize that's different from there being nothing in the arp tables. We should instead print an explicit error to stderr.
