Add boot option pnet (Predictable Network Interface Names)

We plan to use Predictable Network Interface Names by default.

To make that switch easier we added a new boot option "pnet".

The kernel command line option "net.ifnames=0" is currently in every
boot option (except "pnet") but should be removed when Predictable
Network Interface Names works for us.

See: grml/grml#127
