[Clang][Bundler] Fix for a potential memory leak [NFC]

Bundler leaks memory if it is called with -type=o but given input isn't an object file (though it has to have a known binary type like IR, archive, etc...). Memory leak is happening when binary object returned by the createBinary(...) call cannot be casted to an ObjectFile type. In this case returned BinaryOrErr object releases ownership of the binary, but no one is taking it (see line 626).
