NuGet package broken for xbuild builds

[ermshiperete]

When using the libgit2sharp.nativebinaries package on Linux/Mono the files don't get copied over to the output directory because xbuild currently doesn't honor imported ItemGroups.

I think it would be better to use a target instead of the properties.

Where are you seeing this behavior? LibGit2Sharp itself uses the nativebinaries package, and the Travis CI builds use xbuild and everything works correctly there.

Oops, sorry. Now I feel stupid. Yes, it works completely fine, and it's the build script in GitVersion that copies only part of the files. I really shouldn't submit bugs or PRs when I'm not completely awake 😄
