Add support for Arch Linux in render-cloudcfg

 - Detect Arch Linux and set variant accordingly in `system_info()`
 - Allow setting render-cloudcfg variant parameter to 'arch'
 - Adjust some basic settings for Arch Linux in the cloud.cfg.tmpl

The template might need some additional Arch-specific tweaks in the
future, but at least for now the generated config works and contains
the most relevant modules.

Also:
- Sort distro variant lists when adding Arch
- Add debian to known variants in render-cloudcfg
