Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

This allows file and directory permissions work as intended.
cmake is now filled with 'sudo' but with sudo timeout this should be
fine.
