[Buildroot] [PATCH buildroot-test] scripts/autobuild-run: create host-distro file

[Heiko Thiery <heiko.thiery@gmail.com>]

Sometime autobuilder failures occure only on a specific distribution. To
ease the research for the maintainer/developers add a file with that
information to the result archive.

The distribution information comes from '/etc/os-release' and the
PRETTY_NAME value is used from This file. This seems to be present on
the most common distros:

Debian: https://manpages.debian.org/testing/manpages-de/os-release.5.de.html
Ubuntu: http://manpages.ubuntu.com/manpages/bionic/man5/os-release.5.html
Red Red: https://www.freedesktop.org/software/systemd/man/os-release.html
Open-Suse: https://en.opensuse.org/SDB:Find_openSUSE_version
