Subject: [PATCH] selftests: netfilter: nft_zones_many.sh: set ct sysctl after
 ruleset load

nf_conntrack_udp_timeout sysctl only exist once conntrack module is loaded,
if this test runs standalone on a modular kernel sysctl setting fails,
this can result in test failure as udp conntrack entries expire too fast.
