[teamshow]: Add * to indicate if the state has been synced into database (sonic-net#395)

Although teamd would indicate a team member is selected or not, due to
teamsyncd issue, it is possible that the state is not correclty synchronized
into the application database.

Add this '*' to indicate if the member port's state is not written into the
database.
