Daniel Borkmann 497fa510ee selftests/bpf: Add test for add_const base_id consistency
Add a test to verifier_linked_scalars that exercises the base_id
consistency check for BPF_ADD_CONST linked scalars during state
pruning.

With the fix, pruning fails and the verifier discovers the true
branch's R3 is too wide for the stack access.
