Title: Fix guestinfo for Gentoo

The arp command lives under /sbin on Gentoo. Since that's not part of the default user PATH, can_run can't help us, so this solution seems to be the easiest one. I also considered parsing /proc/net/arp directly but I'm not sure how that would work on non-Linux systems.
