Corinna Vinschen fe2545e9fa Cygwin: don't use unlink/rename POSIX semantics on certain NTFS 
If a host NTFS is mapped into a Hyper-V isolated container, the
OPEN_BY_FILE_ID filesystem flag is missing, just as if that NTFS
is a remote drive.  However, NtQueryVolumeInformationFile claims
the drive is a local drive.

We can use this fact to learn that the process is running under
Hyper-V, and that the Hyper-V isolated process can't use rename/unlink
with POSIX semantics.  Strange enough, the POSIX_UNLINK_RENAME filesystem
flag is still set...
