Workaround for redirection at linux side.

As far as I see does python query GetFileType for the handle from stdin which
returns in the redirected case FILE_TYPE_DISK.
Therefore it looks like python calls GetFileInformationByHandle
and expects this to succeed.

In the case of a redirection created by cmd in native or wine
this works as expected.
But GetFileInformationByHandle fails if the redirection is
done at linux side because fd->unix_name gets not set.

Attached patch should demonstrate the issue and possible workaround.
