Yukihiro "Matz" Matsumoto af6f23ddb3 mruby-string-ext: fix String#prepend with self-referencing arguments ...

String#prepend(s, s) read RSTRING_LEN(argv[i]) in the copy loop after
mrb_str_resize had already updated the receiver's length, causing the
memcpy to write past the allocated buffer.

Detect self-references with mrb_obj_eq() and read from the memmoved
original data at p + total_prepend_len using the captured self_len.
This also handles mixed cases like s.prepend("X", s) where earlier
writes would otherwise corrupt the source of later reads.
