[Buildroot] [git commit branch/2025.02.x] package/libsvgtiny: add patch to fix GCC 15.x build issue

[Titouan Christophe]

commit: https://git.buildroot.net/buildroot/commit/?id=82ba9e3547dfec54f6b079daf080cec08e84c718
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.02.x

Add a small, easily backportable patch to fix GCC 15.x build
issue. The issue is also fixed upstream in later releases, but this
patch is a minimal fix that can be backported to LTS independently
from a version bump.
