[ Upstream commit d7d5311d4aa9611fe1a5a851e6f75733237a668a ]
When user test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run.
Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Add an explicit check for module presence and return skip code if module isn't present.
Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.
