Subject: [PATCH] util: always check for ebtables/iptables binaries, even when
using firewalld
Even though *we* don't call ebtables/iptables/ip6tables (yet) when the
firewalld backend is selected, firewalld does, so these binaries need
to be there; let's check for them. (Also, the patch after this one is
going to start execing those binaries directly rather than via
firewalld).
