[OE-core] [PATCH 8/8 v6] package_rpm: Verify that the package manifests are not empty

[Mark Hatle]

An empty manifest will cause a failure condition.  We ensure that any install
actions occur only with a manifest larger then size 0.  Also ensure that padding
is added to the end of the manifest, instead of the beginning to enable this
size check.  (Padding is required for very small manifest files..)
