systemd: restore the prebuilt
ldconfigcache atomicallyOverride
ldconfig.servicefor qcom-distro SOTA images to reuse the linker cache generated duringrootfsconstruction instead of scanning all libraries again on first boot, effectively saving 600-700ms running the service.Copy the cache to a temporary file and atomically rename it into place so concurrently starting processes cannot observe a truncated cache. Fall back to
ldconfig -Xwhen either cache is unavailable.
