Running prepare_rootfs on TARGET_DIR deletes the opkg state when
CONFIG_CLEAN_IPKG is enabled, making the per-device rootfs package install
fail.
To avoid this, create a copy of the TARGET_DIR before prepare_rootfs is run
and use this as basis for per-device rootfs generation.

opkg's -l option is always interpreted relative to the installation root.
This leads to very weird paths inside the rootfs (containing the whole path
to the LEDE tree on the build machine) and causes the subsequent deletion
of the list directory to fail (cluttering the resulting images).
Instead, use the default list directory and remove its contents in
prepare_rootfs.
