selftests/bpf: Fix test_lwt_seg6local.sh hangs

OpenBSD netcat (Debian patchlevel 1.195-2) does not seem to react to SIGINT for whatever reason, causing prefix.pl to hang after test_lwt_seg6local.sh exits due to netcat inheriting test_lwt_seg6local.sh's file descriptors. Fix by using SIGTERM instead. Signed-off-by: Ilya Leoshkevich <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
