Re-adding bnep0 check into oref0-setup.sh (#1179)

* Update oref0-setup.sh

Adding bnep0 check back into script but writing it to the `/etc/network/interfaces.client` file instead of `/etc/network/interfaces` and doing so after the copy of `/etc/network/interfaces` to `/etc/network/interfaces.client`

* Update oref0-setup.sh
