Subject: [PATCH] Use lsb_release fallback code if "import distro" fails

With python 3.8, the standard python "platform" module doesn't
provide the "dist()" function any more. The "distro" module is
used instead. However, not all distributions ship the "distro"
module by default. Catch the resulting exception, and use the
already existing fallback code to determine the distribution
using lsb_release.
