x86: change /dev/console to tty to fix job control

Job control is turned off because it cannot obtain controlling terminal on
/dev/console, so it is impossible to do any job control operation behind
real x86 device (keyboard+monitor or virtualized).

This patch switches /dev/console to tty devices for ash on x86 generic target.
