Subject: [PATCH] Add express <cstdlib> inclusion to format.h

This is preventing nodejs to compile with LLVM's libcxx, missing definition to malloc.

Reference: Gentoo bug 977376 at https://bugs.gentoo.org/977376
Rebased onto node-v26.11.0 for this overlay: 26.11.0 updated the bundled LIEF
and the old context (`#include <cmath>` under FMT_MODULE) moved, so the
26.6.0 copy only lands "with fuzz 2". Portage prints that and still returns
SUCCESS. Only the context lines changed; the + lines are byte-identical.
