zdtm: check lazy-pages and page-server exit status after test is gone

Browse Source 
When running with --lazy-pages or --remote-lazy-pages, the daemons should
run in the background, rather than complete before t.stop() is called.
Many tests try to verify things are ok after test_waitsig() and that's
exactly the place where they access memory and cause page faults.
