[PATCH libinput] doc: specify the https path for mathjax

[Peter Hutterer]

freedesktop.org always serves https for the documentation. if Mathjax is
pulled in from http, browsers reject it [1]

Let's take the default doxygen value but just add the https to it. In the
future we should just ship a copy of mathjax with our documentation.
