realtek: scripts: fix error in belkin-header

For some reason the new belkin-header.py script works without issues
in a local Fedora build environment. In the OpenWrt build pipeline it
produces the following errors:

Traceback (most recent call last):
  File "/builder/shared-workdir/build/scripts/belkin-header.py", line 92, in <module>
    head = create_header(buf, args.belkin_header, args.belkin_model)
  File "/builder/shared-workdir/build/scripts/belkin-header.py", line 68, in create_header
    head[28:29] = VERSION1.to_bytes(1)
TypeError: to_bytes() missing required argument 'byteorder' (pos 2)

This may be related due to different python version. Fix this by
handing over the needed parameters
