[PATCH v4] package_manager.py: correct the deploydir when packagefeed-stability inherited

[<mingli.yu@windriver.com>]

From: Mingli Yu <Mingli.Yu@windriver.com>

After create_packages_dir added in below commit:
85e72e1 package_manager: Filter to only rpms we depend upon

When add below line into conf/local.conf
INHERIT += "packagefeed-stability"

There comes below error when do_rootfs
Exception: FileExistsError: [Errno 17] File exists: '/$Prj/tmp/deploy/rpm-prediff/i586/initscripts-1.0-r155.i586.rpm' -> '/$Prj/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/oe-rootfs-repo/rpm-prediff/i586/initscripts-1.0-r155.i586.rpm'

def create_packages_dir(d, subrepo_dir, deploydir, taskname, filterbydependencies):
  [snip]
  bb.utils.remove(subrepo_dir, recurse=True)
  [snip]

In create_packages_dir function, there is a logic
as bb.utils.remove(subrepo_dir, recurse=True) to
clean subrepo_dir which is actually as example is
/$Prj/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/oe-rootfs-repo/rpm.

But currently when inherit packagefeed-stability class,
the deploydir should be /$Prj/tmp/deploy/rpm-prediff,
not the default /$Prj/tmp/deploy/rpm.

If use /$Prj/tmp/deploy/rpm, then result in the
logic as below:
os.link("/$Prj/tmp/deploy/rpm-prediff/i586/initscripts-1.0-r155.i586.rpm", "/$Prj/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/oe-rootfs-repo/rpm-prediff/i586/initscripts-1.0-r155.i586.rpm")

Update to the actual deploydir to guarantee the logic
as below:
os.link("/$Prj/tmp/deploy/rpm-prediff/i586/initscripts-1.0-r155.i586.rpm", "/$Prj/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/oe-rootfs-repo/rpm/i586/initscripts-1.0-r155.i586.rpm")
