Fixes:
* Remove the "echo '# Remove manifest padding....' > remove.manifest,
The remove.manifest would be used via "rpm -e `remove.manifest`",
there would be error since there is no pkg called: Remove, manifest or
padding
* The incremental.manifest can't be null when used by rpm, so check it
before use.
* The rpm needs:
--root "${target_rootfs}/install"
when use:
-D "_dbpath ${target_rootfs}/install"
Otherwise it would use the ${target_rootfs} as the root, and use the
${target_rootfs}/var/lib/rpm as the dbpath, this is OK in a fresh
installation, but there would be errors when increment rpm generation.
