[PATCH ipset 0/5] ipset test updates

These are extensions to existing test cases, no tests are
disabled and all tests are expected to pass regardless if
the rhashtable patch set is applied or not.

1) Introduce IPSET_MACHINE_SLOW to prevent ipset test timeouts on slow
machines. Increase the slack value to 30s when this flag is set.

2) Prefer tail -n in hash:net.t tests to avoid Fedora 44 error.

3) Use diff -u instead of cmp in tests to improve error readability.

4) Add a UaF reproducer to hash:net,iface.t. Verify that deleting
non-existing elements fails without triggering an incorrect free.

5) Add a test for CIDR matching with the "multi" flag in match_target.t.

Florian Westphal (5):
