  Log Message:
  -----------
  [NFC][sanitizer] Return nullptr from PlatformDemangle

Use fallback name only on the top level, in Symbolizer::Demangle or
DlAddrSymbolizer. This makes PlatformDemangle to be more consistent with
SymbolizerTool and the loop in Symbolizer::Demangle which iterates over
all availible options.
