This fixes several problems in the dhcpcd service: * A segfault during startup, due to a race with udev (dhcpcd would get an ADD event from udev, causing it to re-add an interface that it already had, leading to a segfault later on). * A hang/segfault processing "dhcpcd rebind" (which NixOS calls after waking up from suspend). Also, add "lo" to the list of ignored interfaces. It usually ignores "lo", but apparently not when it gets an ADD event from udev.
