llList2ListStrided is broken when # of elements in the list <= 1.

This issue was found by Serie Sumai when coding the Ruth 2v4 HUD. His comments:

"I see the differences shown here in llList2ListStrided() when the src list has one element. As shown in the output lines 9 through 13, Second Life returns the single element no matter the stride where Halcyon returns an empty list for all tested stride values.

Only strides 0-4 are shown as that is the order of magnitude I was working with in the code where I discovered this difference."
