oe-pkgdata-util: allow reverse package name lookups 

Add a -r/--reverse option to the lookup-pkg subcommand to enable looking
up the recipe-space package name for one or more runtime package names.

Also make this subcommand into a function that can be reused elsewhere.

(From OE-Core rev: f0af7471e688047c7bac5130457e5f9cc2fd5107)
