Stephanos Ioannidis df3d4d27a4 tests: kernel: sleep: Fix uninitialised variable warning
This commit sets an initial value of 0 for the `elapsed_ms` variable,
which may be used uninitialised when the while loop below does not
execute.

This fixes the "‘elapsed_ms’ may be used uninitialized" warning
generated by the GCC 12.

Title: cooperative thread  Sleep and Wakeup APIs

Description:

This test verifies that cooperative  sleep and wakeup APIs 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

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