linux-libc-headers-yocto: move to meta-yocto

linux-libc-headers-yocto is not directly required in meta, so we can
safely move it to meta-yocto.

Machines including meta-yocto that are using linux-yocto that need headers
which are completely up to date with the linux-yocto git tree can use this
as their preferred linux-libc-headers.
