The new standard for host distribution identification [1] is /etc/os-release, and a number of newer distributions provide this file, so add support for this in order to pick up more distributions. Additionally, handle "rolling release" style distributions that don't report a version number, e.g. Arch Linux. With this change we can identify the most common distributions, so this should satisfy [YOCTO #4271]. Note that this doesn't imply support for these distros as build hosts, just that we can identify them.
