Update packaging for latest Rust and Legal guidelines (ctc-oss#951)

A couple of updates brought over from the rpm repo.

Update Rust build dependencies to use `%cargo_generate_buildrequires` to
generate, rather than explicitly listing dependencies. Projects with
subcrates were not originally supported but have been now for a while.

Update the license listing to include Rust statically linked licenses.

See https://src.fedoraproject.org/rpms/fapolicy-analyzer/pull-request/16

Closes ctc-oss#949
