net_gen: replace net_gen with libc
The libc crate provides all functionality provided by the net_gen crate. Removing the net_gen crate reduces the maintenance burden. The switch to libc required some fixes, most notably the switch from a `Vec<u8>` to a `CString` for the `net_util::Tap.if_name` field.
