oe-selftest: devtool: add more explicit check for ls output

test_devtool_deploy_target is failing on the Yocto Project autobuilder
apparently when it attempts to cut out some fields from the list. It
doesn't fail here and I can't see what the problem lines are, so add a
check for lines with too few fields so we can get a look at them next
time it fails.
