[Plugin] Apply cmd predicates to add_cmd_output

If no predicate was passed to add_cmd_output() calls, then a predicate
set by set_cmd_predicate() was not being applied to those calls, thus
leading to a 'None' predicate being evaluated and potentially causing an
exception in plugins such as docker where the bulk of command collection
is gated by the service running.

Now if no predicate is handed to add_cmd_output(), and a cmd_predicate
has been set, then the cmd_predicate is applied before being handed off
to the _add_cmd_output() helper.

Fixes: #1756
