kni: add build option to disable preempting

This patch introduces CONFIG_RTE_KNI_PREEMPT_DEFAULT flag. When set to 'no',
KNI kernel thread(s) do not call schedule_timeout_interruptible(), which
improves overall KNI performance at the expense of CPU cycles (polling).

Default values is 'yes', maintaining the same behaviour as of now.
