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!
