[PATCH v2] selftests/binderfs: Add CONFIG_USER_NS dependency

[Wake Liu]

The binderfs selftests, specifically binderfs_stress and
binderfs_test_unprivileged, depend on user namespaces to run.

On kernels built without user namespace support (CONFIG_USER_NS=n),
these tests will fail.

Instead of adding a runtime check, indicate the dependency on
CONFIG_USER_NS in the selftest config file. This allows the
test runner to skip the tests if the required config is not enabled.

V1 -> V2: Use selftest config to declare dependency instead of a runtime check.
