binman: Refuse to replace sections for now Binman interfaces allow attempts to replace any entry in the image with arbitrary data. When trying to replace sections, the changes in the section entry's data are not propagated to its child entries. This, combined with how sections rebuild their contents from its children, eventually causes the replaced contents to be silently overwritten by rebuilt contents equivalent to the original data. Add a simple test for replacing a section that is currently failing due to this behaviour, and mark it as an expected failure. Also, raise an error when replacing a section instead of silently pretending it was replaced.
