  A dummy interface cannot be deleted using --rmtun because openvpn tries
to send some ioctl (i.e. TUNSETPERSIST) which is not supported by this
device type. This results in the following error:

2022-04-07 09:59:29 Cannot ioctl TUNSETPERSIST(0) ovpn-dummy0: Bad file descriptor (errno=9)
2022-04-07 09:59:29 Exiting due to fatal error

and the interface is not deleted.

Use iproute to generically delete an interface.
