Differential gate: both ElfFile backends over a real corpus.

The comparison happens in-process. Address, size, hotpatchability, symbol
count and ordering are compared strictly and any mismatch aborts. The
demangled name is a rendering and is counted instead -- see the note in
rust/shims/ObjectUtilsRust/RustElfFile.cpp.
