RecursiveDir metadata is lost if glob is expanded through a msbuild task in targets

Repro:

```
s:\work\repro_rohit_target_recursivedir>type test.proj

s:\work\repro_rohit_target_recursivedir>msbuild /v:m
```

The impacted scenario is ```dotnet.exe pack``` , which provides an extension to run a target in inner build to pack tfm specific content into a package. Due to this bug, users cannot provide globbing paths and expect pack to construct the target path in the package based on RecursiveDir value.
