rootfs_deb: move the lock from WORKDIR to DEPLOY_DIR_DEB

* There would be race issue if we put the lock to the WORKDIR, for
  example:
  bitbake core-image-sato core-image-sato-sdk

  If the lock is in their own WORKDIR, the apt-rootfs.conf and
  Packages.gz maybe be written by two tasks at the same time, which
  would cause unexpected errors.

* Create ${target_rootfs}/etc since the "tar -C" needs it.

Note:
  * The rpm has put the lock to DEPLOY_DIR_RPM
  * The ipk doesn't need it since it has locks for each deploy directory
    and put the opkg.conf in his own WORKDIR, which doesn't like deb put
    the apt-rootfs.conf in ${STAGING_ETCDIR_NATIVE}/apt/.
