Changed paths: M libnozzle/tests/test-common.c

Log Message: ----------- nozzle: don´t leak tun/tap interfaces in test suite

the need_tun() test check to verify that the kernel module for tun/tap is loaded, was opening a generic /dev/tun (or /dev/tap) to verify the presence of the kernel module.

On linux, closing the fd to the tap/tun device is enough to destroy the device.

On BSD the device is set to DOWN on closing the fd, but it´s not destroyed.

Stop leaking by gathering ifr ioctl info from the generic interface created by BSD and pass it to the ioctlfd to destroy.
