GH-39919: [C++][Dataset] Add missing Protobuf static link dependency (#40015)

### Rationale for this change

We need to link system libprotobuf.a too when we link libarrow.a, ORC is enabled and system Protobuf is used.

If we don't link system libprotobuf.a, some symbols are missing.

### What changes are included in this PR?

Add missing `${ARROW_PROTOBUF_LIBPROTOBUF}` to `ARROW_STATIC_INSTALL_INTERFACE_LIBS`.

### Are these changes tested?

Yes.

### Are there any user-facing changes?

Yes.
* Closes: #39919
