[PATCH v2] 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'

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 parameter deploydir passed to create_packages_dir is
still /$Prj/tmp/deploy/rpm as example, it should be
/$Prj/tmp/deploy/rpm-diff. Otherwise, there is a logic
os.link(l, dest) in create_packages_dir function will
result in below logic:
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")

Actually doesn't clean /$Prj/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/oe-rootfs-repo/rpm-prediff
, need to update the deploydir to make the
logic changed as below to fix the do_rootfs failure
s.link("/$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")
