[PATCH] sysvinit-inittab: Make sure new shell from start_getty gets a controlling tty

["Yong, Jonathan" <jonathan.yong@intel.com>]

Without exec, the processes from the new shell do not get a ctty:

	root@intel-corei7-64:~# ps -x | grep getty
	  755 tty1     Ss+    0:00 /sbin/getty 38400 tty1
	  791 ?        Ss     0:00 /bin/sh /bin/start_getty 115200 ttyS0
	  804 ?        S      0:00 grep getty

In particular, the openssh client fails:

	root@intel-corei7-64:~# ssh -v <target>
	<truncated>
	debug1: read_passphrase: can't open /dev/tty: No such device or address
	Host key verification failed.

This patch fixes those errors.
