Package and publish the Linux version with dark mode on keybase.io

So that it can be picked up by package maintainers for many Linux distros out there.

Switching from Arch to NixOS, I find myself missing the dark mode a lot. Tried to build from master with an overlay but ran into issues since Client seems to need a specific set of APIs to be supported on the keybase and kbfs services.

Start by reviewing how the Linux client is built from master and which APIs the Client requires from the keybase and kbfs services. The work is done when a Linux package can be picked up by distro maintainers and the Linux version includes dark mode on keybase.io.
