arm/edk2-firmware: ignore buildpath warnings

Latest oe-core has enabled the buildpaths QA check, which warns if the
build paths are present inside binaries. This is because build paths in
deployed binaries is both information leakage and non-reproducible.

Until this is fixed in edk2-firmware, skip this check.
