[OE-core] [PATCH 1/1] archiver.bbclass: fix can't create diff tarball

[Dengke Du]

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.
