Change the xRunningPrivileged check from "!=true" to "==false" (#109 )

The expected behaviour of portIS_PRIVILEGED is:
- return 0 if the processor is not running privileged.
- return 1 if the processor is running privileged.

Some TI ports do not return 1 when the processor is running privileged
causing the following check to fail: if( xRunningPrivileged != pdTRUE )

This commit change the check to: if( xRunningPrivileged == pdFALSE ). It
ensures that the check is successful even on the ports which return incorrect
value from portIS_PRIVILEGED when the processor is running privileged.
