I get a qemu hang on kirkstone, swtpm and optee. One of the
optee-test/xtest hangs the qemu machine in some kind of deadlock.
While this needs to be debugged and fixed, the oeqa runtime tests
also hanged and never returned. Thus this patch set. With these changes
qemu deadlock is detected and do_testimage() task eventually exits
with all correct tests failing and the hangin qemu system gets killed.

Tested on kirkstone and cherry-picked to master. If something blows up
I'll do more testing on master branch based setup.

v2: removed all debug prints

v1: https://lists.openembedded.org/g/openembedded-core/message/176192
