ramips: append tail to WF2881 initramfs image
Stock firmware has a vendor-defined tail at the end of uImage for image validation. This patch enables OpenWrt installation from stock firmware without having to access the UART console. Installation via web interface: 1. Flash **initramfs** image through the stock web interface. 2. Boot into OpenWrt and perform sysupgrade with sysupgrade image. Signed-off-by: Sungbo Eo <mans0n@gorani.run> (cherry picked from commit be3e98ce26da5e737744427e1d59dd1c0508edef)
