util/linuxfw: fix 32-bit arm regression with iptables

This fixes a regression from dd615c8fdd that moved the
newIPTablesRunner constructor from a any-Linux-GOARCH file to one that
was only amd64 and arm64, thus breaking iptables on other platforms
(notably 32-bit "arm", as seen on older Pis running Buster with
iptables)

Tested by hand on a Raspberry Pi 2 w/ Buster + iptables for now, for
lack of automated 32-bit arm tests at the moment. But filed #17629.

Fixes #17623
Updates #17629
