[CI] Fix meson ubuntu ci build

Fix build bug
- Currently, there is a bug in the matrix used in CI where the first Meson build runs successfully but subsequent builds fail due to the presence of a 'build' folder. I would like to fix this issue.
- Before running the Meson build, ensure that any existing folders named 'build' are deleted.

Resolves:
- #2715
