objtool/klp: Match symbols based on demangled_name for global variables
correlate_symbols() will always try to match full name first. If there is
no match, try match only demangled_name.
In very rare cases, it is possible to have multiple foo.llvm.<hash> in
the same kernel. Whenever there is ambiguity like this, fail the klp diff.
