"lazy_sweep" does not appear to have ever been a valid kwarg
for GC.start, however the opposite of "lazy_sweep" appears
to be "immediate_sweep". So use immediate_sweep, and flip
the boolean value of each arg.
I guess this only started failing with r56981 in Dec 2016
("class.c: missing unknown_keyword_error",
commit e3f0cca2f26ba44c810ac980cdff7dda129ae533)
* benchmark/bm_vm1_gc_wb_ary.rb: "lazy_sweep: false" => "immediate_sweep: true"

* benchmark/bm_vm1_gc_wb_obj.rb: ditto
