remote: Delete a now-inexistent API declaration 6fc6eeb66c40310086c8f059cae41de69ad4c6da replaced the remote options with `git_remote_connect_options`. The function definitions were removed, but one function declaration remained, causing linker errors if one tried to use it. This change removes the declaration of `git_transport_smart_proxy_option` to better reflect reality.
