RAPL package ID validation is unnecessary and breaks collections

https://github.com/intel/powertelemetry/blob/5279ae9e8994ee1ecdb98a7ec8e2a0a20bd9e542/rapl.go#L288-L290

This code compares the package ID parsed from path and from the `name` file. However, on machines with the `psys` RAPL domain, we may have `intel-rapl:2` in the path and the name could be `package-0`, depending on how it's enumerated. Having that comparison will return an error in such case and we couldn't collect any stuff for "package-0"
