      Set hangup cause in local_hangup
      
      When a call involves a local channel (like SIP -> Local -> SIP), the hangup
      cause was not being set. This resulted in SIP channels sometimes getting a
      503 error instead of a 486 when the far side sent a busy. In Asterisk 1.8+
      this also can cause issues with CCSS that involve a local channel. This patch
      sets the hangupcause for one side of the local channel to the other in
      local_hangup for outbound calls.
