Not sure if people call spdxcheck.py stand-alone. checkpatch.pl calls it
using "python scripts/spdxcheck.py" which AFAICT should still be python2
on all machines. The shebang-line also uses "python" and not "python3".

So for now this is only cosmetic (unless there are distros that install
Python 3 as "python").

Best regards
Uwe
