The initial fix for localversion setting in 6.3+ broke older recipes and also broke recipes setting localversion in a kernel recipe, as make-mod-scripts (and other locations) can trigger a regeneration of files and don't have access to the variable. Moving the setting of this variable to the global namespace doesn't make sense, so we follow the example of the kernel-abiversion and save a kernel-localversion to the build artifacts. Recipes that may regenerate scripts/dynamic files, must depend on the do_shared_workedir of the kernel and use the helper function to read the file storing the localversion.
