chore(reuse): add SPDX licensing for patches/ + apply-llama-patches.cmake

The REUSE license-compliance check (fsfe/reuse-action) failed on the new files:
- cmake/apply-llama-patches.cmake had the license but no copyright -> add inline
  SPDX-FileCopyrightText (mirrors build.sh).
- patches/*.patch is unified-diff format and cannot carry an inline header without
  corrupting the diff -> annotate via REUSE.toml with a patches/** glob, so every
  current and future patch in the directory is covered automatically.

Verified locally: `reuse lint` -> compliant with REUSE 3.3.
