kernel-devsrc: make tools/Build optional

kernel-devsrc fails to copy files for v6.12+ as the
following upstream commit has removed the file tools/build/Build:

   commit ea974028a049f2cea4bb6be963ee3e3844a03f6d
   Author: Brian Norris <briannorris@chromium.org>
   Date:   Mon Jul 15 13:32:43 2024 -0700

       tools build: Avoid circular .fixdep-in.o.cmd issues

We make the failed copy of this file non-fatal to support
all kernel versions.
