A quick look at the source of the site, it generates the following javascript.

<script>
    setTimeout(function() {
        window.location.href = "https://doc-0o-a0-docs.googleusercontent.com/docs/securesc/ha0ro937gcuc7l7deffksulhg5h7mbp1/nemv3kbhggb02fn2933p80ec5vsi521t/1512345600000/10410701494873540224/*/0B475ByfcR9n4a1JMVEZxQno2Tmc?e=download";
    }, 300);
</script>

But where does that url come from?

With a little fiddling and watching the console on when it does ask to confirm on google, you can see it does a POST request and returns some json.

)]}'
{"disposition":"SCAN_CLEAN","downloadUrl":"https://doc-0c-9k-docs.googleusercontent.com/docs/securesc/aonp7ed1gjmns5tl5di4fl0psa1cppk8/16panrhf9etu7sqgddkaduij5anokf8t/1512345600000/17294955007197410767/17294955007197410767/0ByzJffaEk18uN2ZLeGlIRGVOaDJmWS1WU1RUN3dXUGdtUUx3?e\u003ddownload","fileName":"install.sh","scanResult":"OK","sizeBytes":4936}

So just mock that with PHP

Make a json POST request to that url, google will respond with the json, then just strip out )]}' json decode it, then use a header to redirect to the file.

<?php
$id = '0B475ByfcR9n4a1JMVEZxQno2Tmc';

$ch = curl_init('https://drive.google.com/uc?id='.$id.'&export=download');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, []);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    ... see notice below
));                                                                                                                                                                          
$result = curl_exec($ch);

$object = json_decode(str_replace(')]}\'', '', $result));

exit(header('Location: '. $object->downloadUrl));

Edit (08-04-18)

Looks like some additional headers have been added, if missing it will throw a 400 Bad Request. No biggie, it's still easy to mock it by looking at the request headers when downloading a file from your own drive. I'm unwilling to share a copy&paste solution, as the above still works you just need to add some headers and StackOverflow is not a free coding service nor am I required to maintain every answer I've ever written. Good luck.
