ptserver: Don't check for noauth before rebuilding

The ptserver database building scripts would check to see if the server
was running from a bosserver with the noauth flag set before performing
a database rebuild.

This means that you can't start ptserver normally, and then configure
the database using pts -localauth, which is the preferred method for
configuring new cells.

Remove the check for noauth. This is slightly risky, as it means that a
corrupt database could be completely erased upon restart. However, we
already check that the dbheader (65k) is entirely blank - which will
protect us against any single page corruption errors.
