hacked strip_executables.sh

[Risko Gergely <risko@lisa.njszki.hu>]

Hello!

I made a commit for strip_executables.sh, because it was buggy, and the
compile didn't work. It got two bugs:
	-it was included ../../common.sh, but the needed is ./common.sh
(because we are run it from boot-floppies directory, and not from
scripts/rootdisk)
	-it was tested the files for stripping with -z ${EXECUTABLES},
while we need a for iteration, because -z can only got one parameter

Sorry, if the commit has got any bad things, I probed it and it's working.
