KVM: selftests: implement random number generator for guest code
Implement random number generator for guest code to randomize parts
of the test, making it less predictable and a more accurate reflection
of reality.
The random number generator chosen is the Park-Miller Linear
Congruential Generator, a fancy name for a basic and well-understood
random number generator entirely sufficient for this purpose.
