[OE-core] [PATCH] devtool: Only register each plugin once

[Ola x Nilsson]

When a devtool plugin is shadowed in a higher-priorty layer the
register_commands method was called on the shadowing plugin once for
each found plugin with that name.  A simple unique operation on the list
of loaded plugins solves that problem.  It may still be a problem that
each plugin - shadowed or not - is loaded and initialized.
