arm64: mm: EXPORT vabits_user to modules



TASK_SIZE is defined using the vabits_user variable for 64-bit tasks,
so ensure that this variable is exported to modules to avoid the
following build breakage with allmodconfig:

 | ERROR: "vabits_user" [lib/test_user_copy.ko] undefined!
 | ERROR: "vabits_user" [drivers/misc/lkdtm/lkdtm.ko] undefined!
 | ERROR: "vabits_user" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined!
