[PATCH container v3 2/2] restore: check systemd nesting

[Elias Huhsovitz <e.huhsovitz@proxmox.com>]

For consistency with `post_create_hook` and `post_clone_hook`, invoke
`check_systemd_nesting` at the end of `post_restore_hook`.

This provides early warnings to the user if they restore a modern
systemd-based container without the required `nesting` feature enabled,
preventing potential boot hangs and reducing troubleshooting time.
