tun: Implement ip link del tunXXX

This greatly simplifies testing to verify I have fixed the problems
with a tun device disappearing when the tun file descriptor is still
held open.

Further it allows removal network namespace operations for the tun
driver.  Reducing the network namespace handling in the driver to the
minimum.  i.e. When we are creating a tun device.
