Kumar Gala 5605da129b tests: kernel: mem_protect: stackprot: Dont inline check_input
When building with LLVM on qemu_x86 we see the compiler ends up
inlining the check_input function.  This breaks the stack overflow
that the test is trying to generate, so mark the check_input()
function as noinline to fix the issue.

Title: Stack Protection Support

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
