kernel: introduce linux-yocto v4.9 recipes

Introducing the 4.9 kernel recipes. 4.9 will be a LTSI kernel, so we
introduce these recipes with the intent that they'll replace 4.1 as
the LTSI kernel, and other older kernels (i.e 4.4/4.8)  once 4.9
shown to be stable.

linux-yocto-tiny and linux-yocto-rt are also part of this commit, but
are placeholders while we wait for their content to be available. They
will build, but provide nothing above the standard kernel at the
moment.
