io_buffer.c: Allow copies between overlapping buffers with #copy and #set_string (#11640)
The current implementation of `IO::Buffer#copy` and `#set_string` has
an undefined behavior when the source and destination memory overlaps,
due to the underlying use of the `memcpy` C function.
This patch guarantees the methods to be safe even when copying between
overlapping buffers by replacing `memcpy` with `memmove`,
Fixes: [Bug #20745]
