    build: revert "make image target wait for initramfs"
    
    This reverts commit 43be5087a915727e7dcb3459e2221f094c70811b.
    
    The change is incompatible with the image builder code.
    Luckily the RT-AC58U is no longer depending on the initramfs
    being available for the target's image generation rules.
