The default Apache configuration (used on Windows, Mac, and unknown
Linux distributions) includes mod_autoindex, which generates directory
listings. These are very useful when running tests in a browser (or
content shell) via Tools/Scripts/run-blink-httpd, as they make it
possible to navigate to the desired test from the HTTP server's root,
instead of having to get the full path to a test in the browser's
address bar.

This CL updates the Debian configuration for Apache 2.4 to load
mod_autoindex, so Debian users can get the same directory listing that
is present on Windows and Mac. The CL also reorders some LoadModule
statements to bring the order closer to the default configuration. This
is intended to make it easier to compare the module lists in the future.

Tested by running third_party/WebKit/Tools/Scripts/run-blink-httpd on
Debian Testing.
