tests: Extract mock library for making hash table deterministic

virHashNew calls virRandomBits to initialize seed for the hashing
function. If a test uses iteration through the hash table to produce
results they may/will be non-deterministic. Extract the mock library
which was used for mac address mapping to be universal.
