[backport] build: suppress array-bounds errors in libxkbcommon
Summary:
This is a partial backport of https://github.com/bitcoin/bitcoin/pull/25436
These occur when building with GCC 12.1.
It might be the case that these would be suppressed by updating the package, but that would also require installing new build tools (meson), as well as potentially more dependencies (wayland).

Test plan
ninja all check-all
- Do Linux cross compilation with GCC >= 12.1
