    Mk/Uses/cargo.mk: Use canonical crate file extension going forward
    
    Crates should have the file extension .crate not .tar.gz.  Cargo
    saves them with that extension and it is also what their original
    name was according to file(1):
    
    $ file rust/crates/*
    rust/crates/better-panic-0.2.0.tar.gz:gzip compressed data, was "better-panic-0.2.0.crate"
    rust/crates/binary-space-partition-0.1.2.tar.gz:gzip compressed data, was "binary-space-partition-0.1.2.crate"
    ...
    
    The only reason we used .tar.gz is that it was that way in OpenBSD's
    devel/cargo/cargo.port.mk module.  At the moment they are all .tar.gz
    but they might have a different format in the future.
    
    Doing a delayed rollout of this over a change-everything-once
    approach to
    
    - not immeditately invalidate all uncommitted port changes or
      external ports
    - not make sweeping changes twice in main and 2021Q2
    
    at the cost of having a transition period where mirrors might have
    to carry both the .tar.gz and .crate tarballs (all crates combined
    are ~600 MiB).
