core-utils - cleanup build rules for target library gnc-core-utils

* Eliminate redundant variables (core_utils_ALL_INCLUDES, core_utils_ALL_LIBRARIES)
  Their values are used directly in target_include_directories and
  target_link_libraries respectively.
  They have been eliminated from the python target because target_include_directories
  and target_link_libraries will correctly propagate these values.
* Use generator expressions for a few conditional compile defines and options
