    mtd-utils: fix flash_eraseall installation conflict
    
    override correctly busybox's applet when CONFIG_FLASH_ERASEALL=y is set
    
    Error: update-alternatives: not linking /builds/image/1.0-r0/rootfs/usr/
    sbin/flash_eraseall to /bin/busybox.nosuid since /builds/image/1.0-r0/
    rootfs/usr/sbin/flash_eraseall exists and is not a link
