Kestrelhttpserver: Update Kestrel 1.1.x to use latest Libuv 1.9.x

[Eilon]

The current public Kestrel 1.1.x is referencing Libuv 1.9.1, but we have a better 1.9.2 build that's public.

https://www.nuget.org/packages/Microsoft.AspNetCore.Server.Kestrel/1.1.2

See related bug for 1.0.x: https://github.com/aspnet/KestrelHttpServer/issues/1898

@moozzyk / @muratg - I'm looking at patch candidates but for this bug I can't remember why I opened it (or its companion bug for 1.0.x). I'm looking at the commits for libuv for 1.9.2 at https://github.com/aspnet/libuv-package/commits/1.9.2 but nothing strikes me as "important" or "better."

Do you have any idea why we'd update libuv from 1.9.1 to 1.9.2 in a patch?

[muratg]

I don't remember why we had these, perhaps we did the update in 2.0.0 branch and decided to take it in 1.x as well?

I'm OK with not taking these in the current patch releases unless @moozzyk has a good reason to take these in.

[Eilon]

Talked to @moozzyk and we need to take this.

This patch is approved for 1.1.x. Please follow the patch creation instructions that were sent by email, and submit a PR to the correct branch.
