test/app/stub: try to unlink sentinel file on app start
For testing purposes, the stub app creates a sentinel file that scripts
can look for to see when the stub is ready to start accepting secondary
processes. We need to wait until after spdk_nvme_probe() completes which
can take a while depending on init time of the SSDs.
The stub app will unlink the file on normal shutdown, but if it crashes
unexpectedly, the file will remain and prevent the stub app from starting
again until user manually deletes it.
So immediately unlink the sentinel file at start of stub_start() - we know
at this point that *if* the file still exists it must be left over from a
crashed stub and not a currently running stub (since we can't get to this
point if there's already a primary process at this shm_id). Then create the
file after the spdk_nvme_probe() is complete.

test/app/stub: enforce stub to only run as a primary process
The stub process is only meant to be run as a primary process, it is not useful
at all as a secondary process. We can use spdk_app_opts::env_context
to specify to DPDK that the process should be initialized as a primary process.
That way if a stub process is already running at the same shm_id it will exit
with error immediately.
