vdso/datastore: Always provide symbol declarations
Allow callers to easily reference these symbols in code that is built
even when the generic datastore is disabled.
As there are no good default no-op variants of these symbols, do not
provide stubs but require users to have their own fallback handling
using IS_ENABLED(CONFIG_HAVE_GENERIC_VDSO).
