spanification: Add #pragma allow_unsafe_buffers to courgette/*

This is a preparation to fix each files.
This CL has no behavior changes.

This patch was fully automated using script:
https://paste.googleplex.com/5614491201175552

Note that in patchset2, change to:
/build/config/unsafe_buffers_paths.txt
was reverted. Indeed, running too many (~3) CQ run touching this file is
making the builder cache much slower. I will bundle every change to this
file in a subsequent CL. I will limit myself to 1-2 CQ run per day.

See internal doc about it:
https://docs.google.com/document/d/1erdcokeh6rfBqs_h0drHqSLtbDbB61j7j3O2Pz8NH78/edit?resourcekey=0-hNe6w1hYAYyVXGEpWI7HVA&tab=t.0
