package_manager: Add rpm v4 support

Currently the package manager code only supports rpm v5. To be useful outside
of OE or with OE layers using v4, it makes sense to add in rpm v4 support. This
takes a patch from "Bartosh, Eduard" <eduard.bartosh@intel.com> and enhances
it to also include versions of the workarounds from poky-eurogiciel to
allow rpm v4 usage with the class for image construction.

(From OE-Core rev: fe21804c296bbb8b2b8b0c29e6e4890bc17f07fc)
