Subject: [PATCH 1/1] tools: add VM_WARN_ON_VMG definition

vma tests compilation yields the following error:

vma.c:732:9: error: implicit declaration of function ‘VM_WARN_ON_VMG’

Fix it by adding missing VM_WARN_ON_VMG() definition.

Fixes: e3a7ae85f87c ("mm/debug: prefer VM_WARN_ON_VMG() to report VMG debug warnings")
