* netdata/packaging: [ci skip] temporary workaround for build-id error during go.d plugin set up

* netdata/packaging: re-arrange package dependencies

* netdata/packaging: use a global version variable and make sure cups will depend on the specific version of netdata, we tightly pair them

* Revert "netdata/packaging: [ci skip] add cups package also"
