[committed] c++: Fix strncmp last argument in dump_decl_name [PR93641]

[Jakub Jelinek]

Hi!

I'm not aware of symbols starting with _ZG that don't start with _ZGR
prefix, but perhaps in the future there might be some.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk as obvious.
