Make String#-@ not freeze receiver if called on unfrozen subclass instance
rb_fstring behavior in this case is to freeze the receiver. I'm
not sure if that should be changed, so this takes the conservative
approach of duping the receiver in String#-@ before passing
to rb_fstring.
Fixes [Bug #15926]
