Fix mysql authentication errors

The mysql-server package on Ubuntu16.04 was recently updated to disallow
unauthenticated root user login over tcp/ip.  This, coupled with pymysql
using tcp/ip whenever host and port is specified causes us to fail to
connect to the database when testing Python3 on Ubuntu16.04.

The fix is to use the unix socket instead.

(cherry picked from commit 748ea39ecd)
