kernel: add dynamic configuration and patching 

This change adds the ability to dynamicaly modify a git based
linux repo during the do_patch and do_configure changes.

The bulk of the work is done by the kern_tools, and the recipe
simply needs to add createme and modifyme scripts to go along
with the existing configme.
