[libvirt PATCH] CONTRIBUTING: Include information on build dependencies

[Andrea Bolognani]

libvirt depends on a ton of packages, so trying to install them
all by using the classic approach of repeatedly running configure
and reacting to each failure by installing the corresponding
missing package will inevitably lead to frustration.

Luckily there's an easy solution to get most dependencies
installed in one fell swoop, and we just need to document it.

+You might still be missing some dependencies if your distribution is

+where you need to be to build successfully from source.
