For completeness, extend the API to support non-persistant device. That requires that nm_platform_link_tun_add() returns the file descriptor. While NetworkManager doesn't create such devices itself, it recognizes the IFLA_TUN_PERSIST / IFF_PERSIST flag. Since ip-tuntap (obviously) cannot create such devices, we cannot add a test for how non-persistent devices look in the platform cache. Well, we could instead add them with ioctl directly, but instead, just extend the platform API to allow for that. Also, use the function from test-lldp.c to (optionally) use nm_platform_link_tun_add() to create the tap device.
