tools/testing/vma: separate out vma_internal.h into logical headers

The vma_internal.h file is becoming entirely unmanageable.  It combines
duplicated kernel implementation logic that needs to be kept in-sync with
the kernel, stubbed out declarations that we simply ignore for testing
purposes and custom logic added to aid testing.

If we separate each of the three things into separate headers it makes
things far more manageable, so do so:

* include/stubs.h  contains the stubbed declarations,
* include/dup.h    contains the duplicated kernel declarations, and
* include/custom.h contains declarations customised for testing.
