[PATCH v2025.09.y 18/58] scripts: Makefile.lib: suppress graph_port warnings for overlays

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

In overlays, often only part of a graph is applied with the rest in the
base device tree, so this warning is seldom useful. Disable it.

(cherry picked from commit c28e8f55611cf8c3d104a245bdffb33ccae5f90e)
