Subject: [PATCH 0/3] tools: testing: Use existing atomic.h for vma/radix-tree tests

De-duplicating this lets us delete a bit of code. 

Ulterior motive: I'm working on a new set of the userspace-based unit
tests, which will need the atomics API too. That would involve even more
duplication, so while the win in this patchset alone is very minimal, it
looks a lot more significant with my other WIP patchset.

I've tested these commands:

make -C tools/testing/vma -j 
tools/testing/vma/vma

make -C tools/testing/radix-tree -j
tools/testing/radix-tree/main

Note the EXTRA_CFLAGS patch is actually orthogonal, let me know if you'd
prefer I send it separately.
