scripts/runqemu: Add serialstdio mode
Its currently not possible to have a console available whilst using qemu in graphics
mode. This is causing some issues for testing autobuilder bringup so all a "serialstdio"
mode to runqemu to accomodate this.
The existing serialstdio internal variable is renamed to allow the new user visible option.
