cliconf: Fix use of multiple prompts in send_command (#41885)

Upon preparing the commands for sending to the device, cliconf converts
the optional prompt to a byte string. However, since there might be
multiple prompts specified, the conversion has to happen for each prompt
individually. Otherwise, wrong regexes will be compiled in
_handle_prompt from network_cli Connection.
