I'm 99.999% sure you don't have to be the host. The only achievement I know you need to host is the 16-person match, and for that you have the be a dedicated host.
Have you by chance downloaded the Red and/or Black map packs in the past? There is a bug that affects some people who got those DLC packs where Survival matches register as Sharpshooter. As a result, it is hard to get the Survival achievement because matches aren't counting towards it.
I think it can take a little while for a match to show up in the list. Have your friend try refreshing it. If they can't find you, send me a FR and I'll try to join your match.
There is a workaround for that bug, but that should be used only when nothing else helps.
