Fix ms/setVSvars.bat for new windows.foundation.foundationcontract & windows.foundation.universalapicontract

[brodycj]

I had to make the following change to build the OpenSSL_1_0_2_WinRT-stable branch using a recent Visual Studio Community 2015 update:

diff --git a/ms/setVSvars.bat b/ms/setVSvars.bat

    goto :eof

 :end

I suspect almost the same change will be needed to the WinRT branch.

FYI @sgrebnov (Sergey Grebnov) made an excellent tool for newcomers like myself to build OpenSSL for Windows 8.1 and Windows 10 UWP at: https://github.com/sgrebnov/OpenSSL-WinRT-build

This is great. Thank you. And thanks for the project pointer.

just FYI i rebuilt my machine with a new SSD and reinstalled VS2015.3, thus i didn't have any legacy SDKs or older versions. I had to modify ms/setVSvars.bat to v3.0.0.0 of universalapicontract. i'm not sure how you are supposed to tell what is there without poking around in file explorer.

set "LIBPATH=%_WKITS10%UnionMetadata\Facade;%_VS14VC%vcpackages;%_WKITS10%references\windows.foundation.foundationcontract\2.0.0.0\;%_WKITS10%references\windows.foundation.universalapicontract\3.0.0.0\"
