Updated version number of MlNetMklDeps package to 0.0.0.6

Fixes #859.

I updated the version number of the package MlNetMklDeps in build/Dependencies.props.

Although ML.NET does not officially support x86 at this moment, the new MlNetMklDeps nuget package contains the x86 binaries.

Change looks good to me. @tannergooding did you have a chance to test the package?

[tannergooding]

I'll be able to finish validating that everything works correctly before standup on Monday

The native builds all succeed. I'm working on a few small fixes to the managed build so it can consume the x86 native bits as well.

Hello @sfilipi and @tannergooding and @artidoro ! I would feel more comfortable if one of you who spent some effort reviewing the PR (to say nothing of understanding what it is for) would also be the one to actually merge it.

This PR enabled ML.NEt to reference the MLNetMKLDeps NuGet package version 0.0.0.6.
This NuGet contains, in addition to the binaries present in 0.0.0.5, also the binaries for windows x86. @tannergooding needs to build ml.net on x86.
