Spec files generated by latest versions of rust2rpm no longer rely on the %version_no_tilde macro, and instead define a %crate_version macro. This is more robust, since it does not rely on the translation from RPM Version back to the original SemVer string (which might or might not be complete / correct).

The only place where the %version_no_tilde macro is still used seems to be the %crate_instdir macro, where it could be replaced as well:

• if %crate_version is defined, use it as the version
• if %crate_version is not defined, fall back to %version
