svn commit: r478931 - head/Mk/Uses

Log:
  Mk/Uses/cargo.mk: Let 'cargo-crates' generate Cargo.lock if it does not exist
  
  This will make maintaining ports easier when upstream does not
  provide a Cargo.lock on its own.
  
  It uses the crate registry and will output the newest crate versions
  available based on the restrictions in Cargo.toml.  As such subsequent
  runs of `make cargo-crates` might not generate the same output.
  Upstream should still be encouraged to provide Cargo.lock if possible.
