clone: use OPT_STRING_LIST for --reference

Browse Source 
Not only does this save us having to implement a custom
callback, but it handles "--no-reference" in the usual way
(to clear the list).

The generic callback does copy the string, which we don't
technically need, but that should not hurt anything.
