ci: github: git clean after rebase

After rebasing the PR on main, the local copy of the repository may
still contain untracked directories and files (for example, the commits
from the pull request are "git mv"ing files out of directories that are
then left empty). Add a git clean so that we run CI in conditions
that are as close as possible to a fresh clone.
