[libvirt] [PATCH] tests: mock virRandomBits to make it endian stable
virRandomBits is implemented in terms of virRandomBytes. Although we
mock virRandomBytes to give a stable value, this is not sufficient to
make virRandomBits give a stable value. The result of virRandomBits will
vary depending on endianness. Thus we mock virRandomBits to return a
stable value directly.
