Reduce duplication in Platform/<os>.cmake files 

Several platform-wide linker flag variables are defined in
Modules/Platform/<os>.cmake files for C and then copied by the
Modules/CMake<lang>Information.cmake file for each language.
We now use this approach for the variables

  CMAKE_EXE_EXPORTS_${lang}_FLAG
  CMAKE_SHARED_LIBRARY_SONAME_${lang}_FLAG
  CMAKE_SHARED_LIBRARY_CREATE_${lang}_FLAGS

to avoid duplication for multiple languages in each platform file.
