test: temporary workaround for #21819

Since the TEST-64-UDEV-STORAGE fails are quite frequent now and the root
cause is yet to be discovered, let's add a kludge that attempts to retry
the test up to two more times in case it fails, so we don't
unnecessarily disturb CIs while the issue is being investigated.

Revert this commit once #21819 is sorted out.
