most: apply conditional backport patch for kernels older than 4.13
This patch makes the recipe apply a backport patch on systems running a kernel older than 4.13. It is needed to avoid build errors due to API changes. v2 (jsmoeller): rewrite as KERNEL_VERSION is not available at parsing stage This requires quite some plumbing and the maxkver (and minkver) should probably go upstream. For now we draft this up here as a bbappend.
