Fixes playwright on linux, as reported in https://github.com/denoland/deno/issues/16899#issuecomment-2378268454. The issue was that we were opening the socket in nonblocking mode, which meant that subprocesses trying to use it would get a `EWOULDBLOCK` error (unexpectedly). The fix here is to only set nonblocking mode on our end (which we need to use asynchronously)
