klp diff names the intermediate __klp_relocs section after the object the
relocation belongs to, and post-link turns that into
.klp.rela.<object>.<sec>. Name it after the wrong object and the kernel
applies the relocation when the wrong module loads, or never.

The fixture is the first here to honour MODNAME: most hardcode
name=vmlinux, so passing -DMODNAME to them silently does nothing and the
test quietly becomes a vmlinux test.

This tests the behavior of commit 07f14d6af9d7 ("objtool/klp: Fix
cross-module klp relocation section naming").
