tunnel: T5879: properly verify source-interface used for tunnels
A tunnel interface can not properly be sourced from a pppoe0 interface when such interface is not (yet) connected to the BRAS. It might work on a running system, but subsequent reboots will fail as the source-interface most likely does not yet exist. (cherry picked from commit 66ce19058b7b8597536ddf63bbca027add2ca8a1)
