gnome-base/librsvg: fix phase definitions

The issue here is the same as with libdovi. If we change the inherit
order back to before 01ba4dc619, then
MULTILIB_USEDEP isn't defined so rust.eclass can't use it for generating
the multilib dep on Rust itself.

Also, add a missing rust_pkg_setup call in 2.57.3.
