Declare chocolatey dependency on VC redist package

Fixes #7376. Currently untested, am on holiday without my build environment.

cc @laszlocsomor, @RNabel, @vmax.

To verify:
1. check out this branch on a Windows computer
1. `cd scripts/packages/chocolatey`
1. in powershell: `./build.ps1 -version 0.23.0 -mode rc -rc 2` (I think 0.23 release is in flight, and rc2 has not been pushed)
    * should produce `./bazel-0.23.0rc2.nupkg` (from memory; filename might vary)
1. `choco install --verbose --yes ./bazel-0.23.0rc2.nupkg`
    * should see `[INFO ] - [NuGet] Attempting to resolve dependency 'vcredist2015 (= 14.0.24215.20170201).' in log, where, previous to this change, would not be present in log.
