Some of the features affect nix dependencies, so we need to have a full feature list available when constructing the nix derivation. This incidentally fixes the bug where we weren't enabling jemalloc on rocksdb in CI/devshells, because jemalloc is now a default feature. It does not fix the more general class of that issue, where CI is performing an `--all-features` build in a nix devshell built for default-features. I am now passing `--no-default-features` to cargo, and having it use our unified feature list rather than duplicating the unification inside cargo.
