Logrotate ContainerLogger may not handle FD ownership correctly

One of the patches for MESOS-4136 introduced the FDType::OWNED enum for Subprocess::IO::FD.

The way the logrotate module uses this is slightly incorrect:

1. The module starts a subprocess with an output Subprocess::PIPE().
2. That pipe's FD is passed into another subprocess via Subprocess::IO::FD(pipe, IO::OWNED).
3. When the second subprocess starts, the pipe's FD is closed in the parent.
4. When the first subprocess terminates, the existing code will try to close the pipe again. This effectively closes a random FD.
