Fix two regressions with RPM introduced with Pyro

Right before the release of Pyro (about a month ago), we noticed a problem with missing automatically determined runtime file dependencies after the transition to rpm4 and dnf. Unfortunately it has taken me quite a while to work out all the details, but here is the result finally.

During the search for the missing dependencies, I also stumbled on another regression where the installed-packages.txt file that is generated by buildhistory turned out to no longer contain the actual package names that were used to create the image, but rather some fictitious source RPM names... The first patch in the series addresses that.

The following patches to the libxml2 recipe, insane.bbclass, buildhistory.bbclass and toaster.bbclass prepare the stage for the changes to rpm and package.bbclass so that they will not break once the automatically generated dependencies are restored.

Then rpm is updated to make it possible to yet again access the runtime dependencies we need, and finally package.bbclass is updated to make use of them.

See the patches, especially the last one, for more in depth information on what went wrong during the transition to rpm4 and dnf, and how to solve it.

I would also like to thank Mark Hatle and Martin Jansa who set me on the right track to find the problem.
