[ptxdist] [PATCH] scripts: fix position sensitive options for tar 1.30

[Michael Tretter]

tar 1.30 reports position sensitive options and returns with an error
code. This causes the following error during barebox prepare.

	tar: The following options were used after any non-optional arguments in
	archive create or update mode.  These options are positional and affect
	only arguments that follow them.  Please, rearrange them properly.
	tar: --exclude '.svn' has no effect
	tar: --exclude '.pc' has no effect
	tar: --exclude '.git' has no effect
	tar: --exclude '*.in' has no effect
	tar: --exclude '*.in.*' has no effect
	tar: --exclude '*/*~' has no effect
	tar: Exiting with failure status due to previous errors

Reorder the arguments to tar and put the --exclude arguments before the
current directory.
