rust: run update-hashes.sh to update hashes

This commit is the result of running

  pkgs/development/compilers/rust/print-hashes.sh 1.57.0

in order to generate the bootstrap hash for
mips64el-unknown-linux-gnuabi64.  This commit is needed in order to
bootstrap nix on mips64el because nix_2_4 depends on rustc.
