Install lsb_release from package

The URL we were using to download lsb_release from no longer works,
install from package so this is not affected by disappearing URL's
in future.

This was originally installed from a URL because the package dependencies
caused a 87M increase in the size of the base image. For fedora the
increase is now 27M which is a little more tolerable.
