Fix directory layout for tools/memory_inspector tests.

Fix directory layout for tools/memory_inspector tests.

This cl rearranges the directory layout for the memory_inspector tests.
This is to ensure that:
 - Every unittest lives side-by-side with the module being tested.
 - The mocks/helper class live in the unittest package.
 - Nobody has to hack the sys.path ever.
 - Every (test and non) module uses the "import memory_inspector.submodule"
   pattern consistently, without creating any namespace ambiguities.
