objtool/klp: Add test for sympos in module objects
klp-sympos.c had no coverage at all. sympos disambiguates same-named
symbols for livepatch, counting from 1, with 0 meaning the name is unique.
Resolving to the wrong one is not a load failure -- it is a patch quietly
wired to the wrong object.
Covers the module path, where the position is a count in symbol table order
and klp diff can work it out from the object alone.
