tools: separate out shared radix-tree components

The core components contained within the radix-tree tests which provide
shims for kernel headers and access to the maple tree are useful for
testing other things, so separate them out and make the radix tree tests
dependent on the shared components.

This lays the groundwork for us to add VMA tests of the newly introduced
vma.c file.
