selftests/bpf: Use its own netns in flow_dissector_skb_less_direct_attach

test_flow_dissector_skb_less_direct_attach() and
test_flow_dissector_skb_less_indirect_attach() each create a netns to
run in, and test_progs may run the two at the same time.

Both name their netns flow_dissector_skb_less_indirect_attach_ns. When
the two tests overlap, one of them fails to create or open the netns,
or loses it to the cleanup of the other one.

Name the netns of the direct attach test after that test.
