scripts/*syscalls.py: sort os.walk() for a more deterministic build

Found by "disordered --shuffle-dirents=yes".

Sorting os.walk() in scripts/subfolder_list.py removes the randomness in
the following files:

  build/zephyr/misc/generated/syscalls_subdirs.txt
  build/zephyr/CMakeFiles/syscall_list_h_target.dir/ or build.ninja

Sorting os.walk() in scripts/parse_syscalls.py removes the randomness
in:

  build/zephyr/misc/generated/syscalls.json
  build/zephyr/include/generated/syscall_dispatch.c
  build/zephyr/include/generated/syscall_list.h

Note my (limited so far) testing did *not* observe any randomness in any
object file that this would address; the main purpose here is to remove
a very large amount of noise in diffoscope.
