scripts: fix missing character '0' issue in linksys image
In the stock firmware of Linksys, there is a '0' after the crc checksum. Validated on EA6350V3, EA7300 and EA7300V2's stock images. Fixes: 892d741259 build: add a script for generating Linksys factory images Signed-off-by: Shiji Yang <yangshiji66@qq.com>
