srr: limit publisched endpoints to GLOBAL scope

Motivation:
When SRR publishes a door, then it expected that the door is accessible
by others. Thus we should publish only globally accessible interfaces.

Modification:
Update SrrBuilder to filter doors with GLOBAL scope.

Result:
The link-local and local host interfaces are not published.
