Fix Windows build: use host_env::errno::errors::EISCONN

youknowone · youknowone · commit 144bb70c6793 · 2026-05-20T23:28:29.000+09:00
c::EISCONN works on unix via libc but the Windows c:: re-export list
does not include it. Route through rustpython_host_env::errno::errors
where EISCONN is mapped to WSAEISCONN on Windows.
