chroot_version_hooks.d: Purge removed dev-rust package versions.

This purges a group of recently removed dev-rust packages because
some developers were running into build breakages due to old copies
of bitflags-1.1.0 remaining installed that depend on dev-util/cargo
which is incompatible with the available versions ofdev-lang/rust.
