The FWUPD_INSTALL_FLAG_FORCE flag has really unclear semantics, and ignoring a
file CRC, checksum or model ID should only be done when using fwupdtool actually
debugging a plugin or firmware parser.
Use the existing --force flag when we want a "gentle nudge" like reuploading
previously processed reports.
I misunderstood the original specification, and it seems even USB-hub-less
devices have the same header location as their "write-through" counterparts.
