Yes, but that seems to break if __init__.py file is found from
${LAYERDIR}/lib/oeqa/runtime/cases.

No idea where this comes from, but it's there. addpylib is doing similar things,
adding paths to sys.path and for this use case this not really necessary as
${LAYERDIR}/lib should not need to be, it only has oeqa directory. I presume
test case loading via testimage.bbclass or OERuntim are adding it. These are
kind
of hard to debug since "bitbake -e" show any of this.
It's a bit odd that layer.conf would need "addpylib ${LAYERDIR}/lib oeqa" for
loading
.txt files but that's not needed for finding and using the oeqa .py test files.
With this change addpylib magic is not needed, at least for finding these
.txt files.
Cheers,
