Subject: [PATCH] setup-container: chmod the binary and improve missing-binary
 hint

When downloading a release asset over HTTP the executable bit is lost,
so checking '-x' would always fail. Check existence instead and chmod
unconditionally. Update the error message to cover the three common
install paths.
