[B][SRU][PATCH] UBUNTU: [Packaging] Expose built-in trusted and revoked certificates

[Dimitri John Ledkov]

BugLink: https://bugs.launchpad.net/bugs/1996892

Kernels have a set of builtin trusted and revoked certificates as a
bundle.

It is not very easy to access them, one needs to either download linux
kernel package source code; or boot the kernel to look up builtin hashes;
and then find certificates externally.

It would be more convenient for inspection to expose these in the
buildinfo package, which already exposes auxiliary kernel information.
