test: remove outdated, non-functioning test

Browse Source 
The timers directory test, utilizing FakeTime, has not worked in
quite a while and is not truly testing Node.js behaviour. If a
similar test is necessary it would be better suited to libuv
on which Node.js relies for timers functionality.

* This test case aims at making sure that timing utilities such
* as setTimeout and setInterval are not vulnerable to time
* drifting or inconsistent time changes (such as ntp time sync
* in the past, etc.).
*
* It is run using faketime so that we change how
* non-monotonic clocks perceive time movement. We freeze
* non-monotonic time, and check if setTimeout and setInterval
* work properly in that situation.
*
* We check this by setting a timer based on a monotonic clock
* to fire after setTimeout's callback is supposed to be called.
* This monotonic timer, by definition, is not subject to time drifting
* and inconsistent time changes, so it can be considered as a solid
* reference.
*
* When the monotonic timer fires, if the setTimeout's callback
* hasn't been called yet, it means that setTimeout's underlying timer
* is vulnerable to time drift or inconsistent time changes.
