[LTP] [PATCH] [COMMITTED] openposix: Fix another three failures

[Cyril Hrubis]

This is a continuation of:

commit 38cc030092a54067a9f08dea0173a0d032a15820
Author: Cyril Hrubis <chrubis@suse.cz>
Date:   Thu Oct 29 15:16:30 2020 +0100

    openposix: Fix two test failures

Where I missed three more testcases that depended on variable being
changed from a different thread or signal handler.

Fixes: 8c22a59107dc (openposix: add "static" to all global variables and functions)
