Typos in the french version of DMUP

Hi,

I found a few typos in the french version of DMUP, which I was
re-reading before agreeing to them as part of my application as DD.

- "suivant le seule opinion" -> "suivant la seule opinion" ;

- "n'ait ni demandés de telles informations" -> "n'ait ni demandé de
telles informations" ;

- "à la messagerie au site destinataire" -> "à la messagerie du site
destinataire"

Cheers,
