fix: Update RPM specific packaging to match RPM naming convention
RPM naming convention says that:
This change removes the code which swapped underscores for dashes in the RPM specific code.
It also moves the code which removes the package_iteration in to an else block and adds an rpm specific work around to not do that. This was done so that non-rpm builds are not affected by this change.
