tcp-stress-test: Pull out thread count as a constant

This PR factors out the number of concurrent threads used in `tcp-stress-test.rs` to a constant at the top of the file.

We at @NixOS had to lower our thread count as the chrooted-builds don't allow that many threads.

This change will make it easier to lower/increase the count in the future (I actually forgot to change the second `1000` when I was working on this). Another benefit is the removal of magic numbers in the test suite.

This is related to https://github.com/rust-lang/rust/issues/35107
