Start named as auth and recursive server in pairwise

Start named as auth and recursive server in pairwise

The script will start the named process configured as both an
authoritative and recursive server for each pairwise ./configure
configuration. The test is considered successful if the named process
runs until the 5-second timeout is triggered, and there is no named.lock
file present, indicating that named did not crash on shutdown.
