ANDROID: GKI: fix ABI diffs caused by GPU heap and pool vmstat additions

Browse Source 
New nr_gpu_heap fields in vmstat file cause ABI differences.
Fix them by adding the fields and we don't print it to vmstat now
as it's out-of-tree.

Bug: 130198686

Test: boot and check /proc/vmstat has nr_gpu_heap
