[PATCH -rc] kbuild: properly exclude linux.tar.gz from tar archive

[Leon Romanovsky]

From: Leon Romanovsky <leonro@xxxxxxxxxx>

Attempt to build rpm-pkg randomly fails in tar stage, with same error
as was reported by Nicolas [1]

tar -c -f linux.tar.gz -I pigz --exclude=./linux.tar.gz --exclude-from=.tmp_filelist_exclude --owner=0 --group=0 --sort=name --transform 's:^\.:linux:S' -C . .
tar: .: file changed as we read it
make[1]: *** [scripts/Makefile.package:58: linux.tar.gz] Error 1
make[1]: *** Deleting file 'linux.tar.gz'
make: *** [Makefile:1657: rpm-pkg] Error 2

The reason to it that tar is dependent on order of command line
arguments and needs to have excluded file before creating it. So as a
solution, touch that file to create it and move --exclude list before
any tar arguments.
