examples/OCFSecure: Add ARTIK board

This patch add the ARTIK board to the list of supported devices.
The blue LED on board (GPIO38) is used for switch resource in the server
program. And the GPIO is controlled by "mraa" library which already used
in the server program.

The "mraa" library is not support the ARTIK board. So to use the raw GPIO
pin number, "raw=true" option is added.
