When zram 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.

Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.
