kernel: Use ^D as eot for os:cmd on unix platforms
This is needed as doing only an 'exit' will only exit the program, but any children started in the program that have stdout/stderr still open will keep the port open until they terminate. i.e. os:cmd("while true; do echo sleep 1; sleep 1; done&"). would block os:cmd forever because the while loop keeps its copies of stdout/stderr open forever. It could be argued that this is correct behaviour, and it is the way it works on windows, but changing this breaks backwards compatability for os:cmd which is not acceptable.
