selftests/bpf: verify mount idmaps reach inode hooks

Extend the BPF LSM selftest to exercise create, link, symlink, mkdir,
mknod, and permission through both the VFS identity idmap and a real
idmapped tmpfs mount.

Record the idmap observed by each hook and verify that every updated hook
receives the mapping used by the VFS operation. This provides regression
coverage for passing mount idmaps through inode security hooks.
