[OE-core] [oe-core] ysvinit-inittab: fix hang issue of series consoles check

[b19537 at freescale.com]

From: Zhenhua Luo <b19537 at freescale.com>

    the kernel boot process hangs when /proc/consoles doesn't exists, check
    the existence of /proc/consoles before executing pkg_postinst script.

    Following is the log when /proc/consoles doesn't exist:
        Running postinst /etc/rpm-postinsts/102...
        cat: /proc/consoles: No such file or directory
        cat: /proc/consoles: No such file or directory
        cat: /proc/consoles: No such file or directory
        INIT: Entering runlevel: 5
        Starting OpenBSD Secure Shell server: sshd
          generating ssh RSA key...
          generating ssh ECDSA key...
          generating ssh DSA key...
        done.
        Starting network benchmark server: netserver.
        Starting system log daemon...0
        Starting kernel log daemon...0
        Stopping Bootlog daemon: bootlogd.
        INIT: no more processes left in this runlevel
