Handle BT.DINF properly 

The section is 0x461 bytes long, not 0x460. The config data is also now
initialised to zero to avoid garbage being written to the SYSCONF.

Because our handling has been wrong forever, we discard older BT.DINF
section backups as using them would result in the section being the
wrong size / incomplete again.
