Avi Kivity e2f4c689b1 tests: loading_cache_test: don't exhaust random number entropy ...

rand_int() re-creates a random device each time it is called.
Change it to use a static random_device, and get random numbers
from a random_engine instead of from the device directly.

This avoids exhausting entropy, see [1] for details.
