bridge: mcast: Avoid arming group timer when (S, G) corresponds to a source
User space will soon be able to install a (*, G) with a source list, prompting the creation of a (S, G) entry for each source. In this case, the group timer of the (S, G) entry should never be set. Solve this by adding a new field to the MDB configuration structure that denotes whether the (S, G) corresponds to a source or not. The field will be set in a subsequent patch where br_mdb_add_group_sg() is called in order to create a (S, G) entry for each user provided source.
