The elecom-header renames the firmware image to v_0.0.0.bin, stores its
MD5 sum as v_0.0.0.md5 and tars both files again.

Both v_0.0.0 files are created as the build user making it harder to
reproduce.

This commit sets the owner/group of both files to root by adding extra
options to the final tar command.
