The patch below implements the following changes:

- Add a dummy Signed-off-by line to the generated patch, such that checkpatch
  doesn't complain that it's missing.
- Sort the names of source files (through ls) before using these, such that
  the generated patch is the same during each run.
- Fixed a bug in #elif handling (this bug is not triggered by the current SCST
  code).

This patch has been tested by comparing the output of the old and the new
generate-kernel-patch script.
