linux-libc-headers-yocto: update to v3.4 and remove unecessary code

Updating the linux-libc-headers-yocto recipe to 3.4. There are blocks
of code and definitions that are handled by the included libc-headers.inc,
so we shouldn't be repeating them in this recipe.

(From meta-yocto rev: ad8456e013907c444d972ad945b8d6e96be1d4f0)
