[OE-core] [PATCH RFC 2/3] package.bbclass: Generate runtime-rprovides data

Currently, given a list of rdepends its near impossible to figure out
which ones are potentially invalid and which might be an RPROVIDES of a
package.
This problem is simple to solve, we can write lookup data into the
pkgdata. This patch does that, accounting for the fact that multiple
packages can RPROVIDE the same thing (particularly with locales). Its
done with symlinks so the performance overhead is minimal.
