erts: Fix spawn driver when env size is above pipe capacity
Symptom: open_port() succeeds, port program never starts but instead seem to terminate with exit_status 150 (EINVAL+128). When: If the command payload buffer (including the entire environment) for the port program is between 1 to 4 bytes above the pipe capacity, which is 65536 bytes on newer Linux, but can be as low as 4096 on older 32-bit Linux. Since: OTP-19.0-rc1.
