[OE-core] [PATCH] classes, conf: Exclude native and nativesdk recipes from libc specific override

[Khem Raj]

Based on suggestions from RP

libc-uclibc and libc-glibc overrides are for denoting
system C library in use on the target and not for the
host therefore we make sure that the override only takes
effect for target recipes only.
