    initrd: Better check the created initrd before installing
    
    Improve mkinitrd.sh to check /sbin/oinit, /bin/sh and /etc/rc on the
    created initrd image to avoid installing a broken one.
    
    Update to use "install" to install the created initrd image to ensure
    user/group of root/wheel and mode of 444.
    
    (The command to remove the temporary initrd image was committed in a
    previous patch due to squashing.)
