print: Update Asus URLs to use more secure HTTPS

Asus set up HTTPS for their site, and redirects to that by default. So,
use this by default, which also saves one redirect.

```
$ curl -I http://www.asus.com/
HTTP/1.1 301 Moved Permanently
Content-Length: 0
Location: https://www.asus.com/
Date: Wed, 04 Oct 2017 11:15:14 GMT
Connection: keep-alive
X-Akamai-Device-Characteristics: desktop
X-Akamai-Device-Model: ; ; cURL; cURL
```

Use the command below to change the occurrences.

```
git grep -l 'http://www.asus.com' | xargs sed -i 's,http://www.asus.com,https://www.asus.com,g'
```
