Title: create-diff-object: don't create __fentry__ dynrelas

This fixes the following issue for a patch which changes a module:

kpatch_create_mcount_sections: 1968: bad first rela in .rela.text.e_show

The first rela is "bad" because the real first rela was converted to a
dynrela and then removed from the rela list.

This is a temporary fix. The more permanent fix should be to allow
lookups in vmlinux for patched modules so we don't create any
unnecessary dynrelas.
