The gensyscalls.sh script itself is GPL-2-or-later, but
the output files are generated from the Linux kernel's
headers, which are generally GPL-2-only. As a non-lawyer,
I'm not sure to what extent copyright adheres in a list
of names-and-numbers, but marking the generated headers
as GPL-2.0-only rather than -or-later seems to me like it
better reflects the intention of the header file authors.
It makes no difference to QEMU in practice because we are
overall GPL-2.0-only anyway.
