[OE-core] [PATCH] readline-native: Fix builds on tumbleweed

[Richard Purdie]

OpenSuse's libreadline has extra symbol information which upsets our uninative
loader as our libreadline is missing symbols with the appropriate versions.

The simplest solution is to add the version information as they're harmless.
