[Buildroot] [PATCH] {linux, linux-headers}: default to 4.19.x

[Buildroot] [PATCH] {linux, linux-headers}: default to 4.19.x

[Peter Korsgaard]

4.20.x is not a long term support kernel, but 4.19.x is (supported until end
2020):
https://www.kernel.org/category/releases.html

With the upcoming Buildroot 2019.02 release being a LTS release, default to
4.19.x instead.

Notice: The userspace API breakage in net_stamp.h causing build failures has
now been fixed in 4.19.14 by commit e4a2ffe9029fd (net: Use
__kernel_clockid_t in uapi net_stamp.h)

Applied to master, thanks. I added some comments in Config.in files to
explain why we use 4.19 and not 4.20+, and so that others don't
mistakenly send patches to bump these versions.
