Makefile: Move some scripts imported from Linux
We have some scripts imported from Linux Kernel: setlocalversion, checkstack.pl, checkpatch.pl, cleanpatch They are located under tools/ directory in U-Boot now. But they were originally located under scripts/ directory in Linux Kernel. This commit moves them to the original location. It is true that binutils-version.sh and dtc-version.sh do not originate in Linux Kernel, but they should be moved by analogy to gcc-version.sh.
