* Remove unneeded libcurl-dev build dep
* Make apt-get operations quieter
* apt repo updates
- store the apt repo gpg pubkey in the repo rather than having to fetch
it every time
- add the apt repo for all the deb builds
- update apt repo URL to deb.loki.network instead of
deb.imaginary.stream
* Use http so that we don't need ca-certificates
The repo packages are already signed so using https really isn't
important.
* Add hack to ignore jsonnet conflicts in deb builds
* Add build machine name to build output
* We don't install any shared libs currently
