numa: fix NUMA compile error when sysfs and procfs are disabled

The vmstat_text array is only defined for CONFIG_SYSFS or CONFIG_PROC_FS,
yet it is referenced for per-node vmstat with CONFIG_NUMA:

	drivers/built-in.o: In function `node_read_vmstat':
	node.c:(.text+0x1106df): undefined reference to `vmstat_text'

Introduced in commit fa25c503dfa2 ("mm: per-node vmstat: show proper
vmstats").

Define the array for CONFIG_NUMA as well.
