run-tests: stop allocating HGPORT3+HGPORT4
The only consumer was test-treemanifest.t, which has been fixed.
In general, you should be able to use killdaemons.py to recycle
ports instead of going over 3 ports (HGPORT, HGPORT1, HGPORT2).
In the future, if you want to add a port, be sure to change
portneeded in _getport.
