selftests: forwarding: add ability to assemble NETIFS array by driver name
Allow driver tests to work without specifying the netdevice names. Introduce a possibility to search for available netdevices according to set driver name. Allow test to specify the name by setting NETIF_FIND_DRIVER variable. Note that user overrides this either by passing netdevice names on the command line or by declaring NETIFS array in custom forwarding.config configuration file.
