gluon-{,web-}mesh-vpn-fastd: add support for null@l2tp method

Browse Source 
THe "null" and "null@l2tp" methods are considered equivalent and always
added and removed together when the method list is "configurable".
"null@l2tp" is added before "null", so it is preferred when the peer
supports both.
