mausezahn: improve random mac address generation
Modify -b option to generate all random MAC addresses.
Improve the random generation algorithm, use nrand48() which fills the
ethernet address in two calls instead of six calls to rand() and six
floating point calculations.
Set the locally administered bit of generated MAC addresses.
