docs: kernel-dev-common: add .patch file extension to SRC_URI files

Patches provided in SRC_URI are only applied if their extension is .diff or
.patch. The examples do not use those extensions and would probably result
in user confusion as to why the patches aren't being applied to the
sources.

Let's fix this by giving them a .patch file extension.
