Subject: [PATCH] Fix empty FLAVOR in scheduled AAR builds

When triggered by cron schedule, `inputs.flavor` is empty since
scheduled runs don't have inputs. The build-aar job was uploading
the artifact as `executorch-.aar` (empty flavor), while
upload-release-aar defaults flavor to "xnnpack" and tries to
download `executorch-xnnpack.aar`, causing a 404.

Add consistent default fallback to "xnnpack" in both build-aar
and check-if-aar-exists jobs, matching upload-release-aar.
