tools/testing/vma: default VMA, mm flag bits to 64-bit

Browse Source 
With all of the sanitisers turned on, setting the VMA and mm flag bits
depth to 128 by default results in overly long build times.

Reduce this to 64 - we can always manipulate these later for testing of
larger bitmaps as needed.
