[PATCH 1/2] Docs: Add cpio requirement to changes.rst

[Bruno Moreira-Guedes <codeagain@codeagain.dev>]

[-- Attachment #1: Type: text/plain, Size: 1182 bytes --]

The install target requires cpio to run the `kernel/gen_kheaders.sh`
script, but it's missing in the requirements list at
'Documentation/process/changes.rst'. This patch adds it to the list.
