 In #23061, we added tests for crypto_rand_double() that test:
 * granularity: low bits being non-zero,
 * distribution: some values above and below half, and
 * inner range: mock crypto_rand() and generate lowest and highest valid
 results.

 We should do the same for:
 * crypto_rand()
 * crypto_rand_int()
 * crypto_rand_int_range()
 * crypto_rand_uint64()
 * crypto_rand_uint64_range()
 * crypto_rand_time_range()
 * crypto_rand_hostname()
