src: remove defunct timer_wrap file

Unused since the excellent refactoring in 2930bd,
which also removed `src/timer_wrap.cc` from `node.gyp`. If you try and
get at the binding on a v11.0-pre build, you'll get an error, since the
file is no longer in the GYP build.

```
Jonathans-MBP:node jon$ ./node -v
v11.0.0-pre
Jonathans-MBP:node jon$ ./node -e "process.binding('timer_wrap')"
internal/bootstrap/loaders.js:81
        mod = bindingObj[module] = getBinding(module);
                                   ^

Error: No such module: timer_wrap
