linux-kernels: Introduce kernelPackagesExtensions 

Presently, we can only override or extend specific versions of
linuxPackages_*. This is not ideal for a overlay which adds a kernel
module or overrides the version for a Linux package because we must
override every version individually. Python has introduced a pattern,
"pythonPackagesExtensions" which is an array of extensions (functions)
to modify a given pythonPackages. CUDA has recently done the same with
_cuda.extensions. Apply this approach to kernelPackages as well.
