Move the SPDX tag to the first line (#137)

Linux kernel coding style requires the SPDX tag to be placed in
the very first line of the generated file. See kernel file
 Documentation/process/license-rules.rst
at chapter 'License identifier syntax', '1. Placement:'.

Move the SPDX tag in the python script.
While there, adjust also the style of the multi-line comment.
