mysql_connections_per_user: skip internal user "system user"

Browse Source 
This is the user name used internally by mysql for binlog handling (even
though it's not present in the mysql.user table).

The space in the name makes the plugin freak out about an unknown
"system" value.

Number of connections for this interal user is irrelevant.
