Subject: [RFC PATCH v2 5/6] samples: livepatch: init reloc section array and mark as klp module

Create the array of klp relocation sections in the sample
klp_object (even if the array is empty in this case).

In addition, mark the module as a livepatch module so that
the module loader can appropriately identify and initialize it.
