tty: tty_buffer: use __tty_insert_flip_string_flags() in tty_insert_flip_char()
Use __tty_insert_flip_string_flags() for the slow path of tty_insert_flip_char(). The former is generic enough, so there is no reason to reimplement the injection once again. So now we have a single function stuffing into tty buffers.
