[SRU][F/J/N/O][PATCH 0/4] Add list of source files to linux-buildinfo (LP: #2086606)

[Impact]

For CVE triaging, it's helpful to have an exact list of the source files used for a build.
Add that information to the linux-buildinfo packages.

[Test Case]

Check content of linux-buildinfo packages of the individual kernels.

Test packages for Noble, Jammy and Focal:

[Where Problems Could Occur]

Build failures. This does not change the functionality of any of the kernel packages but just
adds another text file to the linux-buildinfo packages so should not cause any user visible
issues.
