scripts: Add ksize.py and dirsize.py
Fixes [YOCTO #5388] These scripts can be useful when working to reduce the size of the Linux kernel and the root filesystem. ksize.py displays the kernel build size by the built-in.o files. dirsize.py displays the various sizes of the components of the root directory. (From OE-Core rev: 26099eb8ac855aa08e5e1a307affe42fe5f43859) Signed-off-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
