The wasip1 TCP echo test introduced in CL 493358 has a race condition with port selection. The test runner probes for a free port and then asks the WASM runtime to listen on the port, which may be taken by another process in the interim. Due to limitations with WASI preview 1, the guest is unable to query the port it's listening on. The test cannot ask the WASM runtime to listen on port 0 (choose a free port) since there's currently no way for the test to query the selected port and connect to it. Given the race condition is unavoidable, this test is now disabled by default and requires opt-in via an environment variable. This commit also eliminates the hard-coded connection timeout. Fixes #61820.
