FBSD: Use vm_object_mightbedirty when available

Browse Source 
FreeBSD commit 67d0e29304805e43b17e5c27e5a6c566d800a24c (Replace
OBJ_MIGHTBEDIRTY with a system using atomics...) removed the
OBJ_MIGHTBEDIRTY flag, effectively replacing it with the
vm_object_mightbedirty() function. Use the new function.
