61197c7a92 improve_kernel_cve_report: add option to read debugsources.zstd
Adding option to be able to import debugsources.zstd directly.
The linux-yocto-debugsources.zstd is generated in every build and
does not require any additional configuration.

In contrast, SPDX_INCLUDE_COMPILED_SOURCES needs to be explicitly
added and increases build time.

8131e57579 improve_kernel_cve_report: do not use custom version
When using the version specified in cve-summary.json, we need to
remove the suffix containing the custom version to match the
versions from the CVEs.

This patch truncates the version from cve-summary.json to use only
the base version of the kernel.

This is only applicable for kernels where the user has added their
own version.

eb31e34477 improve_kernel_cve_report: do not override backported-patch
If the user has a CVE_STATUS for their own backported patch,
the backport takes priority over upstream vulnerable versions.
