tests/shell: add "random-source.sh" helper for random-source for sort/shuf
Commands `sort` and `shuf` have a "--random-source" argument. That's
useful for generating stable, reproducible "random" output.
However, we want to do this based on a fixed seed, while the
"--random-source" expects a stream of randomness. Add a helper script
for that.
Also, use the stable randomness for shuf in the test
"tests/shell/testcases/sets/automerge_0".
