kern-tools: use Makefile provided install rules

Previously the install of the kern-tools was manual and fully controlled by
whatever build system was integrating/using the utilities. To make this more
generic a Makefile is now provided to take care of installing and removing to
DESTDIR.

Updating the kern-tools recipe to take advantage of this new facility.
