[ Upstream commit 8781578087b8fb8829558bac96c3c24e5ba26f82 ]

When static_keys 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.

Added an explicit searches for test_static_key_base and test_static_keys
modules and return skip code if they aren't found to differentiate between
the failure to load the module condition and module not found condition.

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