workflows: Fix leak detection for IPv6-only in IPsec upgrade tests

Commit 8dc7793 ("workflows/ipsec: Skip bpftrace DNS check if IPv4
is disabled") fixed the leak detection when running on an IPv6-only
cluster. It applied to the IPsec E2E and the E2E Upgrade workflows, but
forgot the IPsec Upgrade workflow. This commit fixes it.
