This bring RHEL rust-toolset in sync with the latest Fedora rust-packaging, most importantly: * Fedora's new style (-v vendor) vendoring is implemented. The old RHEL style (-V #) vendoring is still supported, at least until we can convert everything in ELN. * Automatic generation of bundled provides using %cargo_vendor_manifest. However, instead of depending on cargo2rpm, a very stripped-down version of just its parse-vendor-manifest command is provided as a private script, along with a fileattr to call it. Other changes incorporated in this commit: * -Cstrip=none added to %build_rustflags. * --profile rpm is used instead of --release. * Errors in spawned commands are now caught. * Comments and whitespace are synced for easier comparison with Fedora. * --target all is dropped from license and vendor macros, to avoid false alarms from windows crates.
