kernel: allow fragment re-use from any aware kernel

The kernel fragments contained in this layer could not easily
be consumed by any fragment aware kernel not called "linux-yocto".

To make them easier to include, we make the bbappend more generic,
to match any linux*.bb recipe (note: this means it will match
things like linux-atm.bb as well).

To avoid adding the fragments to recipes that can't use them,
or to a version that hasn't been valided, we use the LINUX_VERSION
variable to pull out the major/minor kernel release and then
include a specific version of the .inc file.
