Backport kernel config check logic improvements to Avocado 103 LTS

[dhsrivas]

Description
On Avocado 103 LTS, the kernel config check logic in "check_kernel_config()" validates only /boot/config-{kernel_version}. Relying on a single path is not reliable, since the config file may be missing, deleted, or moved. Supporting multiple locations improves robustness and ensures more reliable detection across different Linux distributions, including RHEL-based and Debian/Ubuntu systems.

Newer versions of Avocado already include commits that address above issues, and they can be backported to Avocado 103 LTS.

Describe the solution you'd like
Cherry-pick commits 9ddd7ec ("feat(linux_modules): Enhance kernel config file search logic") and bca99c2 ("Support reading /proc/config.gz in kernel config check") into the 103lts branch.

Also please cherry pick 241c9cd into 103lts. If this requires a new issue please let me know.

@dhsrivas @bssrikanth we're in the process of moving the Avocado utilities to the autils project. It has a number of benefits, including being able to do releases quite quickly. Would you be interested in proposing those modules to autils instead?

@clebergnu Are you referring to https://github.com/avocado-framework/aautils? Since a couple of cherry-picks pointed above are already in the Avocado core, would it be possible to include them in Avocado 103 LTS? Or do you strongly recommend that we migrate from Avocado core to aautils for our use with avocado-vt and other Avocado projects?

Hi @dhsrivas, we can definitely look into picking fixes for the LTS, but if there's any change in behavior, it wouldn't belong there. Thus, it would be way more flexible to start using AAutils for that, because you could propose both fixes and updates to logic and behavior.

Let me know if that makes sense to you.
