Flatpak: flatpak: arbitrary read-access to files in the system-helper context via oci symlink following

A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control.
