test/ruby/test_method.rb: Fix a random failure during make COVERAGE=1

Browse source 
This fixes the following failure.

```
1) Error:
TestMethod#test_method_list:
NoMethodError: undefined method `<=>' for #<BasicObject:0x00007f7757e7eb60>

      mods = mods.sort_by {|m| m.name }
                 ^^^^^^^^
```
https://github.com/ruby/actions/runs/4699487470?check_suite_focus=true

TestNoMethodError#test_to_s creates an anonymous module whose `#name`
method returns a BasicObject.

f0669fb6cb/test/ruby/test_nomethod_error.rb (L95-L99)

TestMethod#test_method_list uses `ObjectSpace.each_object(Module)` to
gather all Modules and attempts to sort them by `#name`.
But the anonymous module returns a BasicObject, which leads to the test
failure above.
