fix: devtool fix_perms command

PR firecracker-microvm#4856
extended the `fix_perms` devtool command to also fix permissions of the
directory in which we put CI artifacts from `build_ci_artifacts`
command.

Since, we are now calling `fix_perms` from two different "workflows",
i.e. build/test and CI artifacts building, it might be the case that
some of the directories `fix_perms` is trying to fix permissions for,
don't exist.

Add `-f` flag to `chown` command of `fix_perms`, to avoid issues.
