Bug#35754: mysql_install_db does not work if no hostname is set

Browse Source 
Machines with hostname set to "localhost" cause uniqueness errors in 
the SQL bootstrap data.

Now, insert zero lines for cases where the (lowercased) hostname is 
the same as an already-inserted 'localhost' name.  Also, fix a few tests 
that expect certain local accounts to have a certain host name.
