Test case driver-integrity-tests occasionally fails

[Deniz-Eren]

Jenkins console shows the following when the failure happens:

QNX_HOST=/root/qnx710/host/linux/x86_64
QNX_TARGET=/root/qnx710/target/qnx7
MAKEFLAGS=-I/root/qnx710/target/qnx7/usr/include
+ docker exec --user root --workdir /root dev-env bash -c source .profile                     && /root/workspace/dev/.setup-profile.sh                     && cd /data/home/root/build_coverage                     && ctest --output-junit test_results.xml || (exit 0)
QNX_HOST=/root/qnx710/host/linux/x86_64

1/6 Test #1: ssh-driver-baud-tests ............   Passed    6.44 sec
    Start 2: ssh-driver-integrity-tests

Case can be replicated when running VM target emulation with ctest from host. The driver appears to be operating correctly still when this happens, however the test-case itself hangs; most likely on a pthread_join().

Seems to happen more often if multiple instances of the QEmu emulation is running, i.e. local dev instance and Jenkins instance.

Recent robustness changes have eliminated this issue.
