new_variant_fulltest: Fix 207786a0 ("new_variant: Add support...")

The mentioned commit broke new_variant_fulltest for everything non-brya0
by using a separate firmware target for depthcharge. Instead, make this
explicit and only use the separate target for brya0.

BUG=b:193527706 volteer2 passes brya0 passes
