CMakeAddFortranSubdirectory: Make IMPORTED targets GLOBAL

cmake_add_fortran_directory uses imported targets when using the
mingw fortran compiler. This change makes those targets global
in scope so they act just like the real targets that exist when
a fortran compiler exists and regular add_subdirectory is used.
