C++11 remove std::unary_function bases from functors

std::unary_function is deprecated since C++11 and removed in C++17

90% done with regexp magic.
removed obsolete <functional> includes.

The std::unary_function base class was used in 3 places:
* chart2/source/tools/DataSeriesHelper.cxx: lcl_MatchesRole
   is used in a std::not1 function helper who uses the members
   return_type and argument_type.
   - replace deprecated std::not1 with a lambda
* chart2/source/tools/ModifyListenerHelper.cxx:
   lcl_weakReferenceToSame used the argument_type member in the
   operator() parameter.
   - inline the parameter type.
* xmloff/source/chart/SchXMLExport.cxx: lcl_SequenceToMapElement
   used result_type and argument_type in operator().
   - inline the types

Also fix compile error with gcc about finding std::for_each.
