Avi Kivity 829e2508d0 logalloc: fix entropy depletion in test_compaction_with_multiple_regions() ...

test_compaction_with_multiple_regions() has two calls to std::shuffle(),
one using std::default_random_engine() has the PRNG, but the other, later
on, using the std::random_device directly. This can cause failures due to
entropy pool exhaustion.

Fix by making the `random` variable refer to the PRNG, not the random_device,
and adjust the first std::shuffle() call. This hides the random_device so
it can't be used more than once.
