Cygwin: fork/exec: fix child process permissions

- Exec'ed/spawned processes don't need PROCESS_DUP_HANDLE.  Remove that
  permission from the parent handle.

- PROCESS_QUERY_LIMITED_INFORMATION doesn't work for Windows 7 if the
  process is started as a service.  Add PROCESS_QUERY_INFORMATION for
  pre-Windows 8 in that case.
