Prevent segfault in String#scan with ObjectSpace.each_object
Calling `String#scan` without a block creates an incomplete MatchData
object whose `RMATCH(match)->str` is Qfalse. Usually this object is not
leaked, but it was possible to pull it by using ObjectSpace.each_object.
This change hides the internal MatchData object by using rb_obj_hide.
Fixes [Bug #19159]
