'vmstate_dummy' is special and only used for user-mode. Rename
it to something more specific.
It was introduced restricted to user-mode in commit c71c3e99b8
("Add a vmstate_dummy struct for CONFIG_USER_ONLY") but this
restriction was later removed in commit 6afc14e92ac ("migration:
Fix warning caused by missing declaration of vmstate_dummy").
Avoid the missing declaration warning by adding a stub for the
symbol, and restore the #ifdef'ry.
