use sid config

* use a git-build-package config referring to debian-sid and upstream-sid
* also tell git-build-package, that we have no pristine tar in the repo.
fixup depends

* There are no perl dependencies in the golang-go binary.
* There are also no shared library dependencies in the sources
no dh_perl/dh_python

* We don't need these (and many more)
strip everything, except archives

We only have to exclude Go specific archives from stripping, but not the binaries.
