[ Upstream commit 11875ba7f251c52effb2b924e04c2ddefa9856ef ]
Out of the three nc implementations widely in use, at least two (BSD netcat
and nmap-ncat) do not support -l combined with -s. Modify the nc invocation
to be accepted by all of them.
Fixes: 7df5e3db8f63 ("selftests: bpf: tc-bpf flow shaping with EDT")
