[FLINK-8565][tests] Ensure locationBytes.length > 0 in CheckpointOptionsTest
This PR fixes a test instability in `CheckpointOptionsTest#testSavepoint`.
The tests generated a byte array of a random size, which may also be 0. This
caused an `IllegalArgumentException` when being passed to the
`CheckpointStorageLocationReference` constructor.
We now add 1 to the randomly picked size, and compensate this addition by
reducing the upper bound by 1.
