concurrencytest.py: add outSideTestaddSkip for subunit

see: https://bugzilla.yoctoproject.org/show_bug.cgi?id=13663

When running oe-selftest in concurrency mode (e.g. with oe-selftest
--run-tests oescripts.OEPybootchartguyTests -j 4), if a skip occurred
during setUpClass() rather than within individual tests, the entire
suite would show "UNKNOWN" as each test's result. This is because
subunit doesn't know how to handle skips outside of individual tests.
An example of where this occurs is when running the above call to
oe-selftest in concurrency mode on a host machine that does not have
python3-cairo installed.

Patch subunit inside concurrencytest.py to provide a method called
outSideTestaddSkip, which will allow subunit to correctly detect the
skip in setUpClass().
