scripts: python3 fixes and new tool ksum

Browse Source 
'ksum.py' generates a combined summary of vmlinux and module sizes for
a built kernel, as a quick tool for comparing the overall effects of
systemic tinification changes.  Execute from the base directory of the
kernel build you want to summarize.  Setting the 'verbose' flag will
display the sizes for each file included in the summary.
