ci: Remove non-Proton Wine

We previously only had two traces (one for Raven, one for lavapipe)
running via Wine. To support this, the Vulkan container had Debian's
full Wine installation, one from DXVK, and then a third from Proton
which is used by the b2c jobs.

At 600MB each, this was pretty unsustainable. Remove everything but the
Proton ones.
