use commit hash package from zenpip when making deb/rpm

DEMO:
```
~/src/europa/src/golang/src/github.com/control-center/serviced
# plu@plu-9: cd pkg
~/src/europa/src/golang/src/github.com/control-center/serviced/pkg
# plu@plu-9: ls
gitstatus.sh  pkgroot  serviced.default  serviced.service      serviced-systemd.sh
makefile      rpm      servicedef.mk     serviced.supervisord  serviced.upstart
~/src/europa/src/golang/src/github.com/control-center/serviced/pkg
# plu@plu-9: make deb

DEMO2 - set ZENPIP_VERSION to version wanted on zenpip - should error because that file does not exist yet: 
```
# plu@plu-9: ZENPIP_VERSION=0.8.0-develop make clean deb
