Make: update setlocalversion from the kernel
This syncs the localversion generation with the kernel. At least one effect is that a barebox built from a tar archive no longer marks itself as dirty. Also it moves some stuff from a scary Makefile to a not-so-scary shell script. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
