correct FORTRAN_FLAGS options. For some reason hipfort_check was addi…

…ng an unresolved ref to exit_ which should just be exit. So we add -fno_underscoring to the compilation of the libraries. Also, we moved the -ffree-line-length-none to the default value of HIPFORT_COMPILER_FLAGS which now is added to CMAKE_Fortran_FLAGS in the top level CMake. So no need to add this in lib/CMakeLists.txt
