tdf#109240, tdf#112571: don't export dupe built-in named ranges
XclTools::GetBuiltInDefNameIndex(...) only checked for prefix used in
binary Excel format, and didn't recognize OOXML built-in names, which
resulted in saving them twice in OOXML files.
Adapt to check both binary and OOXML prefixes, similarly to
XclTools::IsBuiltInStyleName(...).
Saving "bad" files after the fix will purge bad "_0", "_0_0" etc.
suffixed built-in names due to how GetBuiltInDefNameIndex(...) works.
