ruby_gc_set_params: update malloc_limit when env is set

During VM startup, rb_objspace_alloc sets malloc_limit
(objspace->malloc_params.limit) before ruby_gc_set_params is called, thus
nullifying the effect of RUBY_GC_MALLOC_LIMIT before the initial GC run.

The call sequence is as follows:

  main.c::main()
    ruby_init
      ruby_setup
        Init_BareVM
          rb_objspace_alloc // malloc_limit = gc_params.malloc_limit_min;
    ruby_options
      ruby_process_options
        process_options
          ruby_gc_set_params // RUBY_GC_MALLOC_LIMIT => gc_params.malloc_limit_min

With ruby_gc_set_params setting malloc_limit, RUBY_GC_MALLOC_LIMIT
affects the process sooner.
