2021-02-06netcat.test: reduce flake.Elliott Hughes
Starting two netcats at the same time and expecting them to be able to talk to each is a little optimistic. I don't know whether `sleep .1` will be sufficient, but wanted to try that before going to `sleep 1` since neither the toybox nor the github nor the Android infrastructure is running these tests in parallel, those seconds add up. Right now this has a ~20% flake rate on the Android infrastructure. I was able to reproduce the flake locally with `while true ; do make test_netcat ; done` on my desktop before this patch, but not after. (Though my desktop is way overpowered for just running that, whereas the build servers tend to be pretty busy, which is why I reserve the right to return later with a longer delay.)
