Andrew Boie 9485172677 tests: stackprot: don't set main stack size
This test uses ztest anyway, the default should be fine
just like any other test running under ztest.

k_thread_create() uses a lot of stack, and the main
stack size is very small if ztest is enabled. Do it in
another ztest task instead.

We don't need to mess with the main thread's priority,
just have the alt thread run cooperatively.

Description:

This test verifies that stack canaries operate as expected.

--------------------------------------------------------------------------------

Building and Running Project:

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

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
