Dockerfile: switch back to docker.io/library/rust:alpine image

Browse source 
bincode 2 required Rust 1.85, so our options are to switch to Alpine
edge or to use the rust image. While using the rust image results in a
statically linked binary, this does not actually increase the size of
the image, as we were already using jemalloc, so almost nothing of libc
is actually used.
