buildhistory: Add output file listing package information
Currently, buildhistory does not produce a single file combining relevant
information of installed packages. Produce an output file
"installed-package-info.txt" listing a package's runtime name, buildtime name,
its recipe, version, and size to avoid having to look up each package externally.
Leave the existing package list files as-is for backwards compatibility.
In order to support this efficiently, extend oe-pkgdata-util to accept multiple keys
for its read-value argument.
