util-linux: Improve PACKAGES_DYNAMIC handling for util-linux-native

DEBUG: Assuming util-linux-swapon-native is a dynamic package, but it may not exist
DEBUG: Assuming util-linux-swapon-native is a dynamic package, but it may not exist
DEBUG: providers for util-linux-swapon-native are: ['util-linux', 'util-linux-native']
DEBUG: sorted runtime providers for util-linux-swapon-native are: ['recipes-core/util-linux/util-linux_2.40.2.bb', 'virtual:native:recipes-core/util-linux/util-linux_2.40.2.bb']
NOTE: Multiple providers are available for runtime util-linux-swapon-native (util-linux, util-linux-native)

The PACKAGES_DYANMIC line could match native and non-native packages so
tweak to improve -native handling and avoid the above warnings in world builds.
