overlayfs tests break on plucky

### Bug Description

At least one overlayfs test breaks on plucky:

```
FAILED tests/integration/services/test_lifecycle.py::test_package_repositories_in_overlay - craft_application.errors.PartsLifecycleError: Failed to mount overlay on /tmp/pytest-of-lengau/pytest-13/test_package_repositories_in_o0/work/overlay/overlay: Command '['fuse-overlayfs', '-olowerdir=/tmp/pytest-of-lengau/pytest-13/tes...
```

This seems to be related to AppArmor changes in plucky that I haven't investigated yet (see logs)

### To Reproduce

```
pytest tests/integration/services/test_lifecycle.py::test_package_repositories_in_overlay
```

### part yaml

```shell

```

### Relevant log output

```shell
