[libzip, mono-runtimes, monodroid] Build with msbuild (#1539)

Like e3abe4b, but different: we had another `xbuild`-ism that
`msbuild` doesn't like: the "intermixing" of "strings" and item
metdata within *top-level* item groups.

For example:

	<_MonoCrossRuntimeIntermediateOutput Include="$(IntermediateOutputPath)\%(_MonoCrossRuntime.Identity)\mono\mini\mono-sgen%(_MonoCrossRuntime.ExeSuffix)" />

The above uses item metadata, e.g. `%(_MonoCrossRuntime.Identity)`,
*outside* of a `@(_MonoCrossRuntime->'...')` context, at top-level
scope. The result is a [build break][0]

[0]: https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android-msbuild/857/

	src/mono-runtimes/mono-runtimes.targets(818,5): error MSB3375:
	The file "obj/Debug//%(_MonoCrossRuntime.Identity)/mono/mini/mono-sgen%(_MonoCrossRuntime.ExeSuffix)" does not exist.

Note that the item metadata wasn't actually replaced, and instead was
used literally.

The fix is to replace the above "intermixing" with `@(Foo->...)`:

	<_MonoCrossRuntimeIntermediateOutput  Include="@(_MonoCrossRuntime->'$(IntermediateOutputPath)\%(Identity)\mono\mini\mono-sgen%(ExeSuffix)')" />

This appeases MSBuild, allowing things to build.

Review matches for:

	$ git grep '<.*Include="\$.*%'

and fix any top-level `<ItemGroup/>` matches.
