vcpkg needs git 2.15.0

[Kha]

A suitable version of git was not found (required v2.15.0). Downloading portable git v2.15.0...
Fetching git version 2.15.0 (No sufficient installed version was found)
Could not run:
    'C:/Tools/vcpkg/scripts/fetchDependency.ps1'
Error message was:
    Downloading git...
Exception calling "DownloadFile" with "2" argument(s): "The request was 
aborted: Could not create SSL/TLS secure channel."

Not sure why the download fails, but it would be nicer to have the right version out of the box anyway.

@Kha In the interim, you should be able to do:

choco upgrade git -y

As your first build step, to get the latest git installed on the machine.

That works, thanks!

Also please check this post for another workaround: https://help.appveyor.com/discussions/problems/12405-builds-failing-due-to-github-tls-changes#comment_44780878

You can see that it is just recently fixed at vcpkg side: microsoft/vcpkg@ce53ea0

We will update vcpkg on AppVeyor build worker images, please watch #2051
