oe-pkgdata-util: package-info: Allow extra variables to be displayed
By specifying the -e <var> option one or multiple times, extra
variables available in the pkgdata can be displayed, e.,g,
`oe-pkgdata-util package-info -e SUMMARY -e LICENSE ...`. The extra
variables displayed are quoted since some of them may contain
whitespace.
