[PATCH] selftests: pstore: return Kselftest Skip code for skipped tests

[Shuah Khan (Samsung OSG)]

When pstore_post_reboot test gets skipped because of unmet dependencies
and/or unsupported configuration, it returns 0 which is treated as a pass
by the Kselftest framework. This leads to false positive 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.
