[PATCH] sphinx-pre-install: add support for Mageia

[Mauro Carvalho Chehab]

Add support for detecting and installing missing packages
on Mageia. I opted to use "urpmi" at the install instructions,
as this is present on Mageia since ever. Yet, if I were using
Mageia 6, I would likely be using "dnf", as it is, IMHO,
easier to use.

Tested with Mageia 6.

This patch comes after this series:
	[PATCH v2 0/8] Add a script to check for Sphinx install requirements

With that, IMHO, we're covering the major community-based desktop
distributions that Kernel developers use. 

Yet, it should be easy enough to use the examples there to add support for
more distros when needed, specially if they're derived from the ones there 
(like CentOS, RHEL, SUSE, etc).
