Add build of libuv for supporting Kestrel Web Server

[muojp]

As Kestrel is supposed to be the major web server backend on ASP.NET for Linux, I wanted to give it a try. So, I added build procedure of libuv to satisfy the dependency.

I created and tested my PR against 1.0.0-beta1.
tested automated build on my fork at Docker Hub: https://registry.hub.docker.com/u/muojp/aspnet-docker/builds_history/82573/ and also tested on derived https://registry.hub.docker.com/u/muojp/hellovnext-docker/ for making sure everything works fine.

For double checking, please try this:

$ docker run -p 5000:5000 -di muojp/hellovnext-docker:latest /bin/bash -c "kpm restore && k web"
$ ab -k -n 100 -c 20 http://localhost:5000/
-> ok
$ docker run -p 5000:5000 -di muojp/hellovnext-docker:latest /bin/bash -c "kpm restore && k kestrel"
$ ab -k -n 100 -c 20 http://localhost:5000/
-> ok

+1 for merge. Thanks for the Kestrel Support. It worked for me.

@aminjam thanks for trying!

@muojp great work here, thanks! I confirmed it enables k kestrel on

• aspnet/Home/samples/HelloWeb,
• aspnet/Home/samples/HelloMvc, and
• @davidfowl's HelloWorldVNext/helloworldweb

samples while running inside docker containers. @muojp can you indent lines 15-19 in dockerfiles with one tab to stay consistent with the rest of the file?

LGTM!

cc: @davidfowl to merge once he's happy.

@ahmetalpbalkan thanks for trying out and pointing out indent mismatch. I fixed indent (spaces -> tab), squashed changes and force pushed 🍰

Great work! It works for me as well even with my onbuild scenario.

consider multilining and alphabetising: as per https://docs.docker.com/articles/dockerfile_best-practices/#sort-multi-line-arguments

@friism thanks for pointing out. I updated the PR for sure.
