sysvinit-inittab: fix hang issue of series consoles check

The kernel boot process hangs when /proc/consoles doesn't exists, therefore
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

        done.
