module/lsm: Have apparmor module parameters work with no args 

The apparmor module parameters for param_ops_aabool and
param_ops_aalockpolicy are both based off of the param_ops_bool,
and can handle a NULL value passed in as val. Have it enable the
new KERNEL_PARAM_FL_NOARGS flag to allow the parameters to be set
without having to state "=y" or "=1".
