fix external cache race on concurrent builds

CI / build-test-release (pull_request) Has been cancelled

Details

Two crafter-build invocations resolving to the same external dep both
cloned into <cache>/<name>-<hash>.tmp, corrupting each other's pack
tempfiles. Use a random per-invocation tmp suffix and treat a failed
rename whose destination now exists as the loser-of-the-race case —
discard the local clone and reuse the winner's.
