server: Added simplistic implementation of FSCTL_GET_REPARSE_POINT

The culprit is in msys2-runtime/winsup/cygwin/path.cc in
check_reparse_point_target which calls NtFsControlFile with
FsControlCode=FSCTL_GET_REPARSE_POINT.

This ioctl is not yet supported in Wine, but this very simplistic
implementation in wineserver seems to be sufficient to resolve the issue.
