Description of problem:

While trying to update some dependencies for device-mapper-persistent-data on Fedora/RISCV F37 I noticed that this package might not comply with Rust Packaging Guidelines.

1. The package use vendor directory for the dependencies, instead of packaging dependencies in Fedora.
2. Vendor directory is updated via a separate tarball (are there any modifications?), that also incl. .*a static libraries for winapi:

3. The package doesn't contain any Provides: bundled(crate(foo)) = version for bundled stuff.
4. The package doesn't use required %cargo_prep macro, instead creating it's own .cargo/config file.

Version-Release number of selected component (if applicable):

Fedora 37, device-mapper-persistent-data-0.9.0-8.fc37
