[RFC] procd: Use /dev/console for serial console if exists

[Gaurav Pathak]

inittab.c: Use "/dev/console" character device (5,1) if it
is present, before trying "/sys/class/tty/console/active" in
case if console kernel command line is not provided during boot
and to allow container environment to use it as login PTY console.
