1381: Close file descriptor on drop in TimerFd r=asomers a=crdumoul This change closes the TimerFd file descriptor on drop. Note that the TimerFd will no longer be `Clone` or `Copy`. Since it has a destructor it can't be `Copy`, and if it were `Clone` you could end up trying to use a closed TimerFd, or double-closing the file descriptor. Addresses #1379.
