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.
