Use cargo install --no-track with cargo 1.41

In cargo 1.41, `cargo install` adds a new `.crates2.json` file in the
install root for tracking version upgrades. This would be another file
that `%cargo_install` should remove afterward, but there is also a new
`--no-track` option which disables such metadata files altogether.

This update should be coordinated with the Rust toolchain update in the
distro, e.g. with rust-packaging `Requires: cargo >= 1.41`. The new
option will be rejected as an unstable option on earlier versions.
