[OE-core] nativesdk.bbclass: Remove historical FILES artifact

[Richard Purdie]

Adding everything in ${prefix} to FILES and FILES-dbg is a historical artifact
left over from when this was sdk.bbclass back in 2009.

The BBCLASSEXTEND changes, multilib changes and cleanups to this file
over the intervening time mean this is simply no long needed.

Its also outright dangerous since it can link the packages together
in circular ways which don't make sense. The simplest thing to is
to drop this since it no longer does anything useful.
