You probably don't need to backport all the machinery in ffi_lib_flags
and ffi_lib, you can might get away with using something like:

GlobalSlurm = DynamicLibrary.open(FFI.map_library_name('slurm'),
FFI::DynamicLibrary::RTLD_LAZY | FFI::DynamicLibrary::RTLD_GLOBAL)

That should re-open the library as global.  (storing it in a constant
just keeps the library handle alive, and hence from being closed when
GC is performed).
