When gpio 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.
