Bug#35807 - INSTALL PLUGIN replicates row-based, but not stmt-based

INSTALL PLUGIN and UNINSTALL PLUGIN worked with statement-based and
mixed-mode replication only, but not with row-based replication.

There is no statement-based replication of these statements.
But there was row-based replication of the inserts and deletes
to and from the mysql.plugin table.

The fix is to suppress binlogging during insert and delete to
and from the mysql.plugin table.
