net_utils: Speed up mac address generation 
Using getrandbits supposes a huge speedup:

Py2
In [2]: %timeit random.randint(0, 0xff)
The slowest run took 28.53 times longer than the fastest.
This could mean that an intermediate result is being cached.
1000000 loops, best of 3: 769 ns per loop

In [3]: %timeit random.getrandbits(8)
The slowest run took 54.81 times longer than the fastest.
This could mean that an intermediate result is being cached.
1000000 loops, best of 3: 126 ns per loop

Py3

In [3]: %timeit random.randint(0, 0xff)
The slowest run took 288.80 times longer than the fastest.
This could mean that an intermediate result is being cached.
1000000 loops, best of 3: 1.15 µs per loop

In [4]: %timeit random.getrandbits(8)
The slowest run took 29.15 times longer than the fastest.
This could mean that an intermediate result is being cached.
10000000 loops, best of 3: 109 ns per loop
