Eliminate nanokernel/core sub-directory

Moves all files in this sub-directory up one level, to the main
nanokernel source directory, then deletes the sub-directory itself.

This change  means that all nanokernel source files (with the
excecption of its include files) are now in the main nanokernel
source directory, which is a more intuitive arrangement.
