poky-qemu-[ifup|ifdown]: Use native tunctl
poky-qemu-ifup can run standalone by root in order to configure a bank
of tap devices for later qemu use.
These devices will, if possible, be owned by a specified group to
which qemu users must belong.
If the kernel is too old to support TUNSETGROUP, then it falls back to
setting the tap device to be owned by a particular user, and that user
will be the only one allowed to use it.
Also overall usability improvements to the scripts, usage() help, etc.
