setuptools 82.0.0 dropped support for the legacy 'pkg_resources'
library. While most users of this (including the all important pbr
library) have been updated to remove references to 'pkg_resources' on
current master, this is not true for historical releases. Pin the
setuptools version used on these historic branches and disable build
isolation to work around this.
