    initrdscripts/init-install*: Add rootwait when installing to USB devices
    
    It can take a bit for USB devices to be detected, so if a USB device is
    your rootfs and you don't set rootwait you will most likely get a kernel
    panic. Fix this by adding rootwait to the kernel command line on
    installation.
    
    Fixes [YOCTO #9462].
