Bug#985811: deboostrap: Auto proxy discovery checks legacy option name, doesn't work with auto-apt-proxy

Dear Maintainer,

I noticed that, when auto-apt-proxy is installed on my machine,
debootstrap does not detect it as it should. It turns out that
debootstrap checks for 'Acquire::http::ProxyAutoDetect', while
auto-apt-proxy sets 'Acquire::http::Proxy-Auto-Detect'.

Who's wrong, who's right? `man apt-transport-http` gives the answer:

        Acquire::http::Proxy-Auto-Detect can be used to specify an external
        command to discover the HTTP proxy to use.
        [...]
        This option takes precedence over the legacy option name
        Acquire::http::ProxyAutoDetect.

Please find a patch at:

Cheers,

  Arnaud
