guix-install.sh: Improve prompt_yes_no procedure.
* etc/guix-install.sh (_flush): New function.
(prompt_yes_no): Clear input, then only read the first character, silently.
Add the [Yes/no] string to the message. When a newline is entered by the
user, treat it as the default value, which is "yes".
(chk_gpg_keyring): Remove "(yes/no)" from the prompt message.
(configure_substitute_discovery): Likewise.
(sys_authorize_build_farms): Likewise.
