runqemu: change terminal's INTR key in 'serial' mode

If you are using an image in '-serial stdio' mode, temporarily change the
terminal's interrupt character to 'Ctrl-]' for the duration of the image
run. In this way, hitting 'Ctrl-C' for something running in the image
doesn't accidentally abort the entire qemu session.
