Now that we have updated userfaultfd_api to correctly return EIVAL when a feature is requested but not available, let's fix the uffd-stress test to only set the UFFD_FEATURE_WP_UNPOPULATED feature when the config is set. In addition, still run the test if the CONFIG_PTE_MARKER_UFFD_WP is not set, just dont use the corresponding UFFD_FEATURE_WP_UNPOPULATED feature.
