ci: Improve double checkout where needed

In the main workflow the problem needing a double checkout is that
git may not be available in the containers we are using which causes the
action/checkout to use a tarball. However some of the steps (e.g. meson
dist) need the checkout to be a real git checkout.

Improve the double checkout by doing the first checkout to a local-actions
directory that can be removed after the setup is done. Even if doing it
in a separate dir, the CWD still belongs to a different user as
additional debugs show before removing that directory:

	ls -la .
	total 12
	drwxr-xr-x  3 1001  118 4096 Mar 12 18:35 .
	drwxr-xr-x  3 1001  118 4096 Mar 12 18:35 ..
	drwxr-xr-x 10 root root 4096 Mar 12 18:35 local-actions

	ls -la ..
	total 12
	drwxr-xr-x 3 1001  118 4096 Mar 12 18:35 .
	drwxr-xr-x 6 1001 root 4096 Mar 12 18:35 ..
	drwxr-xr-x 3 1001  118 4096 Mar 12 18:35 kmod

Move the safe directory setting to the cleanup step.

Another alternative would be to use the setup-os action from a "remote"
repository, i.e. kmod-project/kmod/.github/actions/setup-os. However it
would make harder to update it in PRs since it would fetch the action
from a different branch.
