linux-yocto: introduce 4.10 recipes

The 4.10 kernel has been released, so we introduce the linux-yocto
variant.

This version supercedes the 4.4 and 4.8 versions in the tree, leaving us
with 4.1 (LTSI), 4.9 (LTS) and 4.10 (most recent) as the three active
versions.

Build tested against all qemu variants, core-image-kernel-dev + sato,
with musl and glibc as the C libraries.
