Anas Nashif 33592e8aa8 cmake: remove IS_TEST handling 
Depending on a path inside the Zephyr tree to determine if we are a test
does not scale. Also some samples were marked as TEST while they are
not, just to get some options defined for tests.

Idenitfying a test will be addressed in another patch introducing
CONFIG_TEST.

Overview
********
A simple Hello World example that can be used with any supported board and
prints 'Hello World' to the console. This application can be built into modes:

* multi threading

Building and Running
********************

This project outputs 'Hello World' to the console.  It can be built and executed
on QEMU as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: qemu_x86
   :goals: run
   :compact:

To build the single thread version, use the supplied configuration file for
single thread: :file:`prj_single.conf`:

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: qemu_x86
   :conf: prj_single.conf
   :goals: run
   :compact:
