Use ISCNTRL in tui_copy_source_line
This changes tui_copy_source_line to use ISCNTRL. This lets it work
more nicely with UTF-8 input. Note that this still won't work for
stateful multi-byte encodings; for that much more work would be
required. However, I think this patch does not make gdb any worse in
this scenario.
