selftests: netfilter: avoid RULE_REPLACE error when zeroing rule counters
The rpath.sh test fails on certain iptables versions when
attempting to zero all table counters at once via 'iptables -Z'.
The operation returns
RULE_REPLACE failed (Invalid argument): rule in chain PREROUTING
As a workaround, reset counters by iterating over rules and
zeroing them individually instead of using a single RULE_REPLACE
operation.
