archiver.bbclass: fix can't create diff tarball

When enable:

	ARCHIVER_MODE[src] = "configured"
	ARCHIVER_MODE[diff] = "1"

There is no "diff" tarball created, just "configured" tarball created, in log
file: log.do_unpack_and_patch, it said that directory doesn't exist.

This is because when enable "diff" and "configured", system use create_diff_gz and do_ar_configured function respectively.

In do_ar_configured function, it use create_tarball function, and the create_tarball use the function:

bb.utils.mkdirhier(ar_outdir)

So when creating "configured" tarball, there was no "directory doesn't exist" problem and it was created successfully.

In create_diff_gz function, it didn't create the directory "ar_outdir", so it can't create "diff" tarball, and throw the problem that directory doesn't exit.

So we should add the

bb.utils.mkdirhier(ar_outdir)

to function create_diff_gz in archiver.bbclass.
