testsdk: fix skipped testcase output "UNKNOWN" status while multiprocess execution

Usually skipped testcase output "SKIPPED"
[snip serial execution]
|RESULTS - buildgalculator.GalculatorTest.test_galculator - Testcase -1: SKIPPED (0.01s)
|RESULTS - python.PythonTest.test_python3 - Testcase -1: SKIPPED (0.01s)
[snip serial execution]

But if enable multiprocess execution, skipped testcase output "UNKNOWN" status
[snip enable multiprocess execution]
|RESULTS - buildgalculator.GalculatorTest.test_galculator - Testcase -1: UNKNOWN
|RESULTS - python.PythonTest.test_python3 - Testcase -1: UNKNOWN
[snip enable multiprocess execution]

Here is my investigation:

There is a class pairs TestProtocolClient and TestProtocolServer
provided by python3-subunit. The TestProtocolClient generates a
subunit stream of TestResult from a test run, and TestProtocolServer
parses the stream of subunit TestResult.

The class ProtocolTestCase is a unittest.TestCase adapter and it
uses TestProtocolServer to parse the stream of subunit TestResult.

In Yocto testsdk, it forks multiple processes to execute testcases
and use TestProtocolClient to generate TestResult stream; and then
it creates multiple threads to use ProtocolTestCase to parse stream
of subunit TestResult through pipe; finally it passes multiple
ProtocolTestCase as TestCase instance to main process and output
status result.

The problem point is TestProtocolServer parses `skip:' directive
after reading a `test:' directive. Without `test:' directive,
`skip:' directive will be ignored. All above requires SkipTest should
be raised inside a test method rather than setUpClass method.

Throwing SkipTest inside setUp works correctly
