packaging: fixed the permission error when execute "scripts/exynos_*.sh"
script files for dtb were created with 644 permission in the scratchbox even
though i already changed perm to 755. Therefore, build will be failed when
execute "exynos_dtbtool.sh" because it doesn't have 'x' permission.
I tried to touch these files again and it worked well. I suspect that first
patch couldn't apply the file attribute. That's why i made this meaningless
commit.
