lib/oeqa: change behaviour for unskippable tests

When a test module wants to be skipped because it doesn't
apply to the image but it was nevertheless a required
test (one in TEST_SUITES), we issued an warning that it
was a required test and went on with running the module.
Usually all tests in the module failed (e.g gcc tests on a non-sdk image),
but this allowed us to know that something went wrong with the image
(some package/feature didn't make it).

However, instead of just issuing an warning and running the tests
it's better to throw an exception. The traceback will tell us what's wrong,
and we don't run every single test method.
Output will look like this:
--snip--
| NOTE: Test modules  ['oeqa.runtime.ping', 'oeqa.runtime.ssh', 'oeqa.runtime.gcc']
| NOTE: Found 5 tests
| test_ping (oeqa.runtime.ping.PingTest) ... ok
| test_ssh (oeqa.runtime.ssh.SshTest) ... ok

| Traceback (most recent call last):

| Exception:
| Test gcc wants to be skipped.
| Reason is: Image doesn't have tools-sdk in IMAGE_FEATURES
| Test was required in TEST_SUITES, so either the condition for skipping is wrong
| or the image really doesn't have the requred feature/package when it should.
