            Log:
            Replace hardcoded redhat-linux-build with %{_vpath_builddir} via env var

The 0002 patch hardcodes "redhat-linux-build" as the CMake build directory
name in setup.py. This breaks on distros where %{_vpath_builddir} expands
to a different value (e.g. azurelinux-linux-build).

Fix by reading VPATH_BUILDDIR from the environment with a fallback to
"redhat-linux-build" for backward compatibility, and exporting the macro
value in %build.
