drm/ci: uprev mesa version: fix kdl commit fetch

build-kdl.sh was doing a `clone --depth 1` of the default branch,
then checking out a commit that might not be the latest of that
branch, resulting in container build error.

https://gitlab.freedesktop.org/mesa/mesa/-/commit/5efa4d56 fixes
kdl commit fetch issue. Uprev mesa in drm-ci to fix this.

This commit updates the kernel tag and adds .never-post-merge-rules
due to the mesa uprev. It also fixes an issue where the virtio-gpu
pipeline was not getting created with the mesa uprev.
